What I've learned from this and several other videos with real world results is to buy more than 50 bullets at a time when developing loads...like 500 or so.
Don't buy too many of one kind that you haven't tried before in case you wind up disliking them. Then when you settle on what you want in supplies, purchase in higher quantities if the economics and market conditions warrant it.
always buy big. If you like em, they might change em and you’ll wished you had more. If you don’t like em, shoot em to form new brass, speed up new barrels, get scopes on paper etc.
50 is good to see if your rifle likes the bullet. 25 to find a node, 25 to tune and test I find to be good enough for submoa accuracy.
Would suck to buy 500 bullets and your rifle not shoot them as well as another brand/grain/etc.
When I have a hard time falling asleep, I watch this guy, bam out like a light.
It’s Johnny’s reloading bench that does it for me
Is there anyone else you could recommend that is short and to the point, explains things in terms beginners can understand, and backs up theory with (credible) data? BAR is the best I've found so far in these terms. Anyone better that you know of?
Boltactionreloading is like sky diving compared to designhunter
I'm only a hunter, so while I need to be accurate, I don't need to get crazy. Most of my shots will be well under 300 yards. When I'm developing a load I start mid-range in the load data and load up 3 rounds at each charge weight, increasing in .2 grain increments until max (or I start seeing pressure issues). I'll take the best load out of that batch and do 5 rounds at each charge weight at .2 grains under, the same, and .2 grains over what that initial "best group" charge weight it. When I shoot those groups I'll take the best group and call it good.
Any method that conserves materials is pretty gd critical for newbies since materials are no where to be found...

This video / content is really sound, fair, useful, and a great summary of how to go about load development. I have loaded centerfire rifle ammunition for about 45 years and have learned a lot about cartridge loading in that time. I have also shot several long-range competitive matches and have done well, given the competition. There are a lot of great reloading content providers out there, but this video is among the best for straightforward, no-frills, no BS, no heavy opinion information. GREAT JOB and thank you for your work.
Thank you. I appreciate the feedback.
I used to do ocw. Since watching your videos I tried this 10 round method… I agree with the basic premise but with that being said it isn’t a cure all and will still require more ammo to be used but this method is an amazing tool to help ace components instead of wasting them on velocities and charges they aren’t needed at. It helps narrow down the the powder charges to focus on faster with less rounds fired! Thanks for posting this video about this method
I love your honesty. I personally use everyone's info as a stepping stone to finding my own way per cartridge.
Thanks for another interesting video.
I come from a slightly different background when it comes to chasing accuracy. In a previous life, I was in artillery and part of what we do consistently is measure wear in the barrel and velocity at different charges. This information is all recorded so that the database is continually updated and individual computation changes can be made.
Establishing what velocity nodes yield the lowest SD and hence consistency seems like the logical starting point to me. Tuning for accuracy with harmonics related to the projectile and barrel is the next logical step.
Going off groups alone ignores the velocity consistency, which means that your results may not be repeatable.
It's like building a house, there's an order to doing things to produce repeatable and predictable results.
Thank you so much for making this video! This is my 4th time rewatching and I really want you to know I appreciate it and it helps bring into perspective these processes. I tried and succeed my first single ladder test with my 7.5 Swiss and 4166 so I really thought that was it lol meanwhile a single ladder with StaBall in my 6.5 got me no where so I’m doing multiple ladders with multiple primers. Really do appreciate your efforts man they help keep me on track. I’ve probably rewatched more of your videos than any other creator. And I’m sub’d to about 20 different reloaders!
Glad you enjoy the content!
Thank you for keeping this short and for using real targets.
An hour at a white board with comments turned off is useless to me.
Your data also seems to agree with litz. Go till you see pressure, back off a titch and try a few groups (then adjust seating depth)
We all get confirmation bias haha. We see what we want to see. All that matters is rounds on target. I don't see why people get so worked up. Do what gets you the results you need.
As always great video! Thanks man.
Thanks Matt. Glad you enjoyed it. This has been one of my most requested videos and much fewer than normal are watching it, so who knows. At the end of the day everyone needs to do it the best way for themselves. Some guys can shoot in their back yard and some guys have to drive an hour, those things play into the equation.
Thats how i do it. Up to max step back and adjust oal.
Great video. I like seeing the various graphs. I’ve started keeping similar data myself and it was helpful to see yours presented here. Keep up the good work.
Glad you enjoyed it!
I watched the satterlee and Lily video and I couldn't really understand what he was talking about he's not a very good instructor. I got a lot of information from this video that answers a lot of my questions and I appreciate it thank you very much!
Your welcome. You may want to subscribe if you haven't I plan on walking through his process in detail in the future.
Most excellent. Well done
Watched twice and took notes.
Great video man! I use both methods.
I can rely on the Satterlee for my bolt guns, and then do a couple quick follow ups with 3 shot groups to verify so Im not burning alot of components up. Your point on using it as a way to check what velocities youre actually getting is spot on. As an added thing I personally do is I tend to log the hits on the target as I shoot. You will see trends that generally follow the flat spots in the velocity curves. So if shots 4,5,6 are good on the velocity side, youll tend to see those 3 shots group very nicely as well. This is super easy to do if you have something like a Shotmarker system, but I do it with an identical target and a spotting scope.
I use more of an OCW type tests for my my ARs, as the SDs on autoloading rifles tend to be higher than a bolt gun. I always temper my expectations for ARs and their accuracy, and I tend to be not nearly as picky.
Now I have a headache...great video. Wish I were rich also
I appreciate this methodical breakdown, easy to follow, and at least to me, makes sense. I will incorporate this into my next load development for 556
Great job with the video. I usually test 6 successive charge weights in .2 grain increments up to the book max, but with 3 shots at each weight. This gives me a better handle on the velocity/SD I can expect at each charge weight as well as a sneak preview of the node accuracy. After shooting those 18 rounds, I usually have a very good on where I'm going with that component combination and can begin seating depth tests. For my purposes, I'm really not interested in lower velocity nodes or pushing bullets above listed maximums.
I do the exact same thing. Then repeat when I do my seating depth.
Do you shoot 6.5 cm? The book max always seems extremely conservative in 6.5 cm, I've been able to go to 2.5 grains over a published max before seeing any signs of over pressure. I don't recall the exact logic but the published loads used to be higher and they got dropped back for some reason. I'm trying to develop stupidly accurate, hot hunting loads for my buddy whose going after elk beyond 300 yds and the loading maxes are pretty anemic when you look at how much energy you have down range. It seems to me the safety margin is very broad in 6.5 cm.
@@DracoOmnia I do have a 6.5 CM that I use for hunting and long range shooting.
@@DracoOmnia I don’t think that’s exclusive to 6.5 Creedmoor. I think book max charges are always going to be on the conservative side for liability purposes.
@@echofoxtrotwhiskey1595 it's more than just being conservative on the max loads, they literally rolled back the max loads in 6.5 cm specifically and, as I said, they seem even more conservative in 6.5 than in other calibers.
Exactly what I was looking for !
Thank you,,,,
Maybe i oversimplifying things but i usually do about 5 charges of 4-5 rounds up to max in about 1/2 grain increments. If i cant find something decent there, i dont mess with that powder/bullet combo: on to the next one. My thought process is if i have to be within
.1-.2 grain of a load for it to be good, then its not for me (my scales and powder thrower cant produce that level of accuracy consistantly anyways). If i find 2 groups beside one another that are very similar, say 51 and 51.5, ill test another group in the dead center of those two and compare. If its similar then thats my load, as ill have leeway on either side of the charge. Ill then play with seating depth if im feelin froggy, but if its a really good group, ill just leave it at that. Im not going to expend 3-4 times more components to MAYBE ring out another .25 moa.
I completely agree, I’m not looking for fussy loads or rifles. A good rifle isn’t picky on loads and a .5” group should be quickly attained in a good rifle.
That's my method as well. Using increments smaller than .5gr early in development is a waste of time and components.
Next up should be Optimum Barrel Time (OBT Theory) testing vs OCW.
42.7 and 42.9 are clear scatter groups. That would put the 1.5 percent node right around 43 grains. OCW to the rescue. Now, did you really need all that Satteree stuff?
Excellent video! Thank you 🙏🏻 😊😊
Another great video. Always fun to watch.
Glad you enjoyed it
Really enjoyed the presentation. Thank you!
Glad you enjoyed it!
Another very interesting and informative video Sir, I always enjoy your videos, please take very good care of your hand! 😁👍
Thanks Mike. Glad you enjoy them!
Like your stuff. Data is good, lots of data is better. I do like groups that match vertically more than horizontal.
Very cool data, thank you!
Good video BAR! Explained all very well...
Thanks!
I re-watched the original Satterlee Ladder video from 2017 and watched all 3 of the Satterlee-Lilly videos. I don't think that Satterlee has changed his ladder technique at all. The original video is just about ladder versus OCW testing. The new series of 3 videos is about long range shooting, from case preparation, developing a load and then calibrating your equipment to shoot accurately at 1000 yards. 4 years later Satterlee has learned a lot and is paying attention to choosing a BTO that produces a certain group configuration on target. This was probably not even on his radar back in 2017.
Another great video! Thank you!
Glad you enjoyed it!
Really cool video, thank you
The folks that aren't being entertained enough or can't see past the reloading bench talk production are amusing, personally I'm about first round hits on steel at long range from field weight rifles from field positions. The mechanics of equipment and marksmanship are pretty straight forward and fairly easy to quantify, but load development to achieve consistency is where the real magic occurs IMO.
This bro gets it. IMO the 'gold standard' for factory 'match' ammo has traditionally been Federal Gold Medal Match, I've shot a shit ton of it over the years, in many great rifles, some of them I even paid for with my own money haha. IME rifles that don't shoot GMM well and aren't broke are far and few between. GMM is externally loaded to generic SAMMI, that rules out those tweeks, GMM shoots well in all barrel lengths, that rules out barrel harmonics as the bullet exits. That leaves the one thing that can be controlled at the factory and that's load density and ignition variables. I'm pretty sure that folks that are 'chasing the 'lands' are actually tweeking the load density. My bros shake their heads at my pedestrian reloading practices, I don't use expensive 'match' dies, I do measure that the dies are loading straight rounds, once. I FL resize, I set back .002. and lock em down and leave them. I trim, uniform primer pocket dept and flash holes once.
I throw all charges on Lee Perfect's haha. I have done all the Gucci powder handling methods and when the dust settles, the Lee Perfect does just as well and anything else, once I have the charge that optimizes the load density, I lock it down tight and leave it the fuck alone. Mind you, I'm not looking for .25MOA groups ( I can't shoot that well in the dirt), my standard is .50MOA from field positions and I work for a total rifle weight with bipod, sling, loaded around 10lbs ish Yeah my service\match rifle self uses a tight loop sling (Armageddon) when appropriate and of course a light fill rear bag, I see the PRS bros are 'discovering' slings those cosmopolitan hipsters!! (I love the young dudes sheading it up out there rock the fuck on bros :-)
Anywho this is just one mans way of agreeing with the wavy reloader hand hahah
Great video man!
I reload all my ammo and I use the load data that is recommended by the bullet manufacturers to start out. The best I can figure is they know what their bullets can do with different powders and loads. I start in the middle and work out from there . Not everyone has a crono and a range too test at so safety first and happy loading.
Hi Stuart, Exactly my point, everyone has a different situation, goals, tools, calibers, the list goes on. We are all going to be a product of our experiences and there is nothing wrong with doing what works for you.
Great stuff!
Id love to see more on the subject, The only thing I was not thrilled about the powder 6.5 stabal was I was using more powder than many of the different brands and still not getting the speeds I was looking for but over all I can't complain about the groups I got with it I am loving reloading so far but It's hella confusing with all that is involved to me anyway thanks for another great video I'll be watching out for more of them .
And here I was not even knowing there was another way... haha
You always do a good vid. I always enjoy your content.
On the subject of the 10 shot load development, I see so many guys saying things like "CONSISTENT VELOCITY" but, they completely dismiss the fact that 1 shot per charge weight gives anything but consistency &, cannot even give a range or an average.
I've been trying to think of the reason why guys can't seem to see the elephant in the room with this method &, I think it's because guys believe that the figures they see on the chrony are absolute representations which, they are not.
You have done oodles of shot strings over the last few years & have all the proof you need to recognize that, statistics is not about a particular velocity or group size, it's about ranges of velocities & group size, always.
When trying to look into the future which, is exactly what load development is, we must always refer to our results in terms of a range. Take standard deviation (SD) as a good example. How many times have you & others, referred to their SD's with not one mention of the fact that, at best, that SD figure represents approximately 70% of any future outcome with, up to 5% of any future outcome with that particular load, more than likely reaching 3x that of the original SD.
Statistics are ALWAYS about ranges & never absolute figures. The biggest problem with the Satterlee method is that decisions are based on absolute velocity figures where none truly exist. A rifle with 10 cartridges of the exact same load will usually shoot a range of 10 different velocities or, a range of 5 shot group sizes. This is in fact all you & I have ever seen a rifle shoot, with no exception. This alone should convince you that the Satterlee method is nothing but smoke & mirrors.
When I do load development, I look at my results in terms of the likely range based on the SD. Once you start thinking in those terms, load development is less stressful & way more realistic.
I noted you mention that you've been struggling with velocity results with varget. Now I understand that you are probably referring to varget in a comparative sense however, I think it just as likely that because you do so much data heavy load development, all you are actually seeing is the truth of the matter. So much of the subject of load development results on the majority of shooting related channels is simply claptrap in my opinion with 1/4 MOA 3 shot groups & etc convincing the average poor bastard out there, trying to make sense of all this that, he's doing something wrong. The truth is, the average rifle shoots a range between 3/4 & 2.5 MOA &, those are figures collected by ammunition manufacturing companies from many thousands of test shots.
It's long been recognized that 90% of accuracy gains is in using a heavy barrel with everything else divided into the last 10%.
As for velocity consistency, all the most consistent load recipes are well known & only minor tweaks are necessary but, not easily established statistically as real improvements.
What he said
My luck with the Satterlee method hasn't been great, but I accept that some of this may be my doing. As a general rule, I do not anneal my brass and, on top of that, I don't always use top-shelf components. I'm pretty religious when it comes to case prep/equal treatment of brass otherwise.
Still, though, I would like the Satterlee method a lot more if I had a range in my backyard. Even though it's only about a 15-20 minutes drive, going out to the range is usually a half-day affair for me. If I'm really ambitious, I can make multiple trips, and have done so - but it's definitely diminishing returns for time-cost. (And even with the more mobile Summit Press, I'm not going to bring my reloading set-up with me.) The "10-shot load development" really is a misnomer, as in the best case scenario you're spending about 20-bullets with a successful go of it. (Ten for the initial, five to confirm ES/SD, then five to print on paper. This isn't including messing with seating depth, if needed.)
I like options, though, and I like the diversity of trying out different things.
It's 10 shots to find the sd node. 1st rifle (300 Norma) I've used it for I fired a separate string to find max powder load first which added 9 rounds to the count, I did also fire an additional 6 to confirm groups and seating depth but the initial seating depth i used was the best anyway so I shouldn't have worried.
The 2nd rifle (6.5 Creedmoor) i used it with I skipped the max pressure test and just loaded the 10 round string based on Alliant data. Another 10 rounds to confirm groups I was done, accuracy was sub 1/2 inch so I didn't bother with seating depth.
@@bruce6099 If my experience matched and it worked that easy every time for me, I would have a much higher confidence level with the process for what I do. As it stands, I use it testing combinations that I don't have exact load data for, or for when I have to extrapolate. When Staball 6.5 was new, this is what I did to figure out load data for .303 British. Cheers!
Based on your info, I think I'd be inclined to try a 41.8 grain charge and play with seating depth a bit... Nothing wrong with a 2/3 MOA rifle.
I'm trying a method that splits the 2 concepts: loading 3 rounds at each charge weight, then checking SD within each group, group size and variation of velocity between groups (looking for similar "flat spots". 30 rounds to get close, then load another 20 or so to confirm, and still have 1/2 box (50) left to load for use/ calculated a drop chart (I load mostly for hunting purposes)
Hi MIke. Thank you so much for your comment. My hope is that everyone would just look at the data for what it was and adapt it for what makes sense for them. There are advantages to both. I hope it works out exactly the way you plan!
After seeing this video I figured I would give it a try. I just acquired a labradar. I am loading for .338LM and figured this would be a great place to start in figuring out the optimum powder charge. Well I went to the range today. I loaded up 17 rounds X2 from 74.4-82.1 in .3 grain increments. I removed the firing pin assembly and ejector plunger and bumped the shoulders back 2 thousandths on the cases. The bolt was closing freely. I neck size with a short action customs bushing 2 thou under loaded case neck diameter. I ran a .3350 21st century expander mandrel into the neck. I brushed the inside of each neck. I ran two strings and my data looks nothing like yours. The second string is very linear and the first string didn't have any nodes that you speak of. I wish there was a way I could upload a picture. Might be efficient for you but me? My results were useless.
Hi Warren, my email can be found in my channel info. I don't post it to keep the bots away if possible. Having a linear response isn't necessarily a bad thing. understanding how the powder and primer combination ack together is the most important part and hopefully now you have a good idea if your velocities and pressure are matching up with the load data that you had used.
BAR
Have you seen that Scott Satterlee has updated his method to V2.0? It’s featured on Long Rang with the Lillys. Pretty interesting change in that he looks for his optimal length first.
Yes and I plan to try it. It takes me a while to review, come up with a good test example, load it, test it, summarize the results and make a video on it. He still does it this way, just a different order. If you see the video I did on coal vs velocity I am not sure one affects the other enough to matter, but only testing will tell. Something else for everyone to argue about.
@@BoltActionReloading awesome. Looking forward to that video as well. Keep up the good work. Between you and JRB I’m learning a lot that I hope to put into practice soon, just need to find the time to get back on the bench.
Awesome...... Thanks!
You're welcome!
Start with slower powders til you find the seal, then you can really get all you can get out of your weapon
Seal as in no powder residue on the neck??
@@mitchellnebrosky2765 pretty sure he meant "sill". for example czcams.com/video/t5wqWHts6Qo/video.html
This would be great and I'd really like to try these, but I can't find the components anywhere to do it.
love your videos on bit of advice stop worriying about what other people say via their comments and stick to the content. you get to wordy and long who cares if other people challenge your findings just stick to the presentation your videos will improve dramatically
It’s increasingly being proven that larger sample size testing shows all this to be statistical noise - seeking Brian Litz’s work and Hornady podcast episode 50
Put a sock puppet on that hand.
Great video. 👍
Thanks 👍
Good Job!!
Thanks!
Do you shoot the 10 rounds in quick succession, or do you wait a period of time between shots to let the barrel cool? I’m going to try this in the next few days.
Great info but you may want to look into a barrel sponsor lol.. at your rate by the time you find a node to settle on the throat erosion throws you a curveball, not hammering you at all I enjoy your videos, have you tried the dry neck lube yet????
HI JB, I have something in the works that includes this option but life has gotten in the way. It may not be exactly what your hoping for but we can discuss it in the comments section.
I look forward to it. I can’t wait till your channel gets so big that you are testing out different barrels after break in for groups! Proof versus white oak......
Ryan turns off commenting on most his videos lol. can't handle the heat.
What software do you use to plot the point of impact and produce the MOA results?
Thanks . Good info .
I am stumped at the moment . I have established a good velocity node yet the group size is 3'' . I did not get a great group node even with the ladder test at 0.3gr incraments . Will playing with seating depths change group size. ? Being a 6.5x55SE with 103 gr copper pills COAL to jamb is 64.98mm, so I have 7mm to play with , what incramental seating ladder test would you recommend ? The manufacturer recommends 1.5mm. Min jump to keep pressure down the load is almost max @ 3200fps . I'm tearing my hair out as nothing is making sence
Love your explanation and approach. I really appreciate it. I've been disappointed with how expensive it is to develop accurate loads, having to expend so much to reach a good result. An ordered method mini.izes that.
The best load development. Is the method that doesn't blow your face off.
What do you use to make these charts? Is this just an excel thing?
Wouldn’t you hate to run 100 more shots just to get the group size of the max load. I would hold on to it even though the node stuff says otherwise. Maybe run some as the first shot. ( I think it would fall in the case capacity v accuracy theory )
Why do sometimes a higher charge will yield a slightly lower velocity? Ive done this myself i go up by .4gr per round and it seems every 4th round is slightly lower than the one before it, baffles me lol
After watching this I realized how lucky I am to have found my loads 😂
I have a few questions,
1. Is the ogive in the .223 45 grain bullet, in the same location relative to the rifling and the end of the case for a heavier bullet?
2. How are you calculate chamber pressure ?
3. Please explain how you are using standard deviation and what does it give you for an answer to improve your next shot.
4. If everything was perfect to the Nth degree, what is the probability of YOU putting the NEXT bullet in the EXACT SAME hole?
I have a Remington 700 BDL with a heavy barrel in .223. This rifle loves the Winchester 45 grain hollow point USA2232. At one hundred yards I can walk my shots around a one inch target sticker at 3,6,9,12. I want to reproduce what my gun likes. Winchester is very tight lipped. They won’t tell me a thing.
However,
My HOWA 1500 of the same caliber hates everything off the shelf. I have tried different brands of scopes thinking that was the problem. My Anshuetz 17 and that BDL target results, says it’s not me, so, now what do I do? With things changing so rapidly on shooting, I am afraid to go to the local range because of the data collection from just signing my name to sign in for fear that will leave a trail to follow to confiscate things I have.
Thanks
I did check one box of that 45 grain Winchester on the ogive position from the end of the case. The average was plus or minus ten thousandths of an inch. In any case this is still a very accurate round for this rifle. So, what is it, that make this round so accurate?
seatings are a myth or less u got a bench/target gun with a short throat. base standards are to seat the bullet 1 caliber bore bearing surface of the bullet in the case or with light bullets seat until the bore surface of the bullet is flush with the case mouth, then with the longer bullets then i listed above is max coal of your magazine. then bullet your gun likes with a powder that goes perfect with that bullet should get u in there.
That 43.3 load just has some horizontal in it. Would have been a screamer if you were using some windflags.
Thanks for the video. I'm new to the "art" of reloading and have been watching, reading everything I can find to get up to speed. I think we don't have much choice these days - either pay through the nose for factory ammo or reload. I get that you first find the velocity node at the recommended COAL, then fine tune the accuracy node (group size) via bullet seating depth, but you lost me at the end. You seemed to be doing both at the same time, I suspect because you had a few different nodes that looked promising. So you used group size to back into the velocity node, and you ended up with a middle load. A lighter load would give you accuracy but not the energy desired at long range for larger game. The heavy load would give you accuracy but wear out your barrel - and shoulder - faster. Am I making sense?
Super helpful, do you leave the magneto speed on throughout the whole test even when going for groupings? Am I wasting my time by taking it off for groups? I read a lot of forums saying it would affect the barrel
I guess the best answer is it depends. People will swear it makes a huge difference, but I have never seen it. Any more, I have switched to the lab radar, though I don't think it's mandatory for anyone. If your shooting f class and .025moa is going to make your break your day try everything you can I guess.
I like BAR approach which is always do what you want but this is how I do it -- Why do the losers get so bent ... Why try to tell everyone you are oh so right - do what you want and stop tell others they are wrong - why do you care
How do you measure the groups when all rounds are shot at the same target
My head is spinning, and I need a drink.
Did you start the test with a clean or fouled barrel? If fouled, how many fouling shots?
personally I like to take 2-3 fouling shots on a semi-clean/lightly oiled barrel. The key for success is consistency
Question. I thought you were looking for the dip in the data. You keep picking the spike. From what you are showing.
I wish I understood the value of standard deviation over average.
How’s the small rifle primer brass working for you? Have you compared it to standard large rifle primer brass?
Can you still do this load development with new unfired Lapua brass?
Can you tell me which primer. you have had the most consistent and successful results with Varget? A point you made earlier in the video.
Thanks in advance,
MAN
Sellier & Bellot Primers
What formula and program are you using to make the graphs ?
Looks like Excel
Quick question. What is the brand of the ss comparator set you use?
Looks nice and accurate.
They are from short action customs.
The human variable has a much larger standard deviation..then your hand loads…work less on making the perfect bullet and work more on breaking the perfect shot.
Do you also, or could you also use Quickload, to get a quicker/narrowed down end result sooner also?
For me quickload is hit and miss. I love it for cross referencing load results or getting starting load data when I don't have published data, but I have never been able to switch powder, match barrel times and have perfect results. If you have a better way I would love to hear it. I am here to learn as well!
do you have a sd es spreadsheet with graphs that you would be willing to share? Thanks Ken
HI Ken, I am not completely opposed to it, and have on several occasions, but I don't as a general rule as it seems that some folks just have an agenda to push and I frankly don't have the time to argue. I try to show the data as unbiased as possible. Maybe I would make it a Patreon thing in the future or something like that.
I'm sure this is a dumb question, but when I settle on a node to investigate, why is the SD varying so much from group to group? if I build 5 at 41.3 then 5 at 41.5 then 5 at 41.7 everything mechanically is the same, like neck tension, primers, powder, COAL - do I get an SD of 14, then 23 then 9?
It could depend on several things. Is the average velocity the same or does it change?
@@BoltActionReloading this was from exploring a node, so the average v was slightly higher as the grains increased. so how does 0.2 grain step cause SD to increase then decrease? everyone says SD is from neck tension.
@@glycyldi thanks that's true, but the population could be vast, so 30 could be way too small also. And everyone using the load development process is generally using 5 rounds. My point is: everyone says neck tension is the key to consistent low SD's but it looks like powder causes more variability.
Load development gives me a headache...
43.4 is where you should be
What always frustrates me is it seems like the lowest SD is never the smallest group. Just seems opposite to me.
try 3 different powders from fast medium and slowest for the gun ur shooting and see what sd and groups u get out of those.
Anyone that can’t consider and criticizes anyone else’s processes that work for them is an idiot. The smartest people shut their mouths (or fingers), analyze the process, see what they want to consider using in their process and test it out to see if it works for them. Chasing tight groups is a never ending experimentation! There will always be new methods, products and barrels to play with. Thanks for the video!!!
And then you said “a couple of different primers” and I laughed out loud! I can’t even find one primer let alone multiple different kinds! Thanks for Covid China!!!
Aslong as the results are repeatable and can be applied on other platforms... Then i don't really care what the method is because statistically all the systems are very simular
Good info! I would suggest talking a little slower. It is a lot of information for someone to absorb when not as initially familiar with it as you are.
Say lapua like that again
Sorry, couldn't handle the shaking hand.
So 10 shot is a misnomer...
Hi Drew, it reference the number of rounds to figure out where you can identify a powder charge that should give you consistent velocity. I would never call a load done after 10 rounds and you likely would still need to tune COAL and still yet validate that charge weight that you identify is in fact what you think it is. Though I do find this information valid, you really need to have your reloading process nailed down for it to be effective.
I do not associate max loads and accuracy. It has not been common in my experience. I start .005 off the lands and mid charge from Lyman. Many .5” groups using this method, no need to chase ghosts
Another OCW that's not even close to true OCW, it's easy to knock OCW when you're not doing real OWC.
With a goal of finding a load using the least amount of components, for let's say, an off the shelf hunting rifle, I think the best method would be to load up 10 rounds for the velocity node test at 30k off jam, and pick the middle of your favorite node. Load up 3 rounds at a few different depths (-30k, 50k, 70k) and choose the one that performs the best. That's 19 rounds. Anyone been successful at this? I just can't find precious powder and primers, so all the workup shown here is not possible for me.
You have some really great content. But stop waving that hand. It's a video and all we get is hand waving? Come on.
Lapua lololololol
You got poor group and spoke too much. If you can consistent get group as 0.25”, That is much better than you spoke.
If you cons. achieve 1/4" MOA, somebody need ta sign you up.....AIN'T POSSIBLE
Who does groups on load testing? Seating depth will tune any load. Find speed node....don't worry about groups, then find depth group node. Start 20 thou out from jam and do seating depth every 3 thou. This guy has fouled his barrel and gone a big distance wearing a barrel out. For what a 6.5 creedmoor? Hahahaha...would hate to see what he does for a BR or F class. Depths for groups and after that ass a barrel tuner and fine tune even more.
