[DO NOT TRY THIS EXPERIMENT IN ANY WAY SHAPE OR FORM- this test was conducted with hands-on help from world-class experts]
A lot of you have missed the point of this video: This is a SCIENTIFIC TEST to demonstrate a few things:
1. The increased pressure capacity that Alpha Munitions brass can handle
2. The amazing strength of Bat actions, see czcams.com/video/VkvFtlTEuSc/video.html for more info
3. The IMPORTANT relationship between chamber, brass, and resizing die - see in-depth video here: czcams.com/video/5oOdQbDq1kE/video.html
This is NOT a suggestion that 308 Winchester can replace a 300 Win Mag.
[[[We got within 98.2% of Nosler's 300WM Max data]]] Here's the math: Nosler lists 10 powders/loads for 300WM 210 grain (average max load = 2807.8 fps), and 10 powders/loads for 300WM 220 grain (average max load = 2700.3 fps). The middle ground (215gr equivalent) between these is 2754.05 fps. We achieved 2706.3 here with 308, so that's 98.2% of what Nosler lists as equivalent 300WM max performance for a 215 grain bullet.
That's Noslers load data. You don't think you could push beyond that? Hard to believe you couldn't get more out of the 300 WM with a higher chamber pressure and larger case capacity. Would've been a cool video. Anyway, keep it up.
@@Rumpleforskin2000 That's our 308 performance compared with Nosler's 300WM data :)
308 the same longer barrels slower powders
Gavin, that’s simply amazing that you were able to achieve that kind of pressure and still not get most of the signs usually seen, not even at 90 KPSI!! Great work!!👍👍
Forgive my ignorance. Does that mean that if it was possible to use steel case, you could have gone higher in pressure?
somewhere in kentucky a man named scott is touching his neck
OMG! You may be close to the mark!
Holy fuck 😂
😂😂😂 I hope Scott see this!!
Neck tingle
Can you post your email address Gavin please
This experiment speaks volumes about the quality and structural strength of BAT actions, Alpha brass and Gavin’s machining work.
Thank you!
I've heard of cryo treating barrels, I'm rebuilding an engine now and reading about how much stronger cryo treated parts are, has anyone tried cryo treating an action and bolt to find out how much stronger it is???
@@RockKnocker17it really depends on the steel alloy, but for some, cryo treatment does indeed increase performance. This usually comes in the form of more toughness for the same hardness, or higher hardness for the same toughness. But other alloys don't benefit from it.
I have a feeling Alpha Muntions will be busy cranking out .308 cases for many many months as a direct result of this video. 👏 Im a big fan. Great content. Thanks!
Bubba's pissin'-hot handloads
Now, do this same test with a 300 Win Mag. 24-26" test barrel with the 215 gr. If you can reach 3100fps+ then you guys are certified badasses.
If Alpha made 300WM brass, I'd be all over that!
@@UltimatereloaderPeterson makes 300 Win Mag brass.
@@rsquared9703 Peterson makes their brass so good people are running in excess of proof pressure and getting 10x reloads on it.
@@randomidiot8142 proof is double the max pressure. Wherever you got that information is wrong
@@Ultimatereloader Broz on long range only has tons of data on the 300wm with 215's fyi
One of the few not clickbait videos i've seen in a long time. Good entertainment.
Thank you!
Well, then you're going to love my next video on how I've ramped up stock .45-70 cartridges to 4,950 ft/sec velocities and 20mm Oerlikon energy(50,000 ft/lbs), but with standard pressures, using 480gr lead flat nose "cowboy load" bullets. My PPPP(proprietary patent pending powder) is obviously incredibly impressive for black powder! 😁
Ammo test was good and all, but I can’t get over the view! Absolutely stunning.
Thank you, my favorite place to go! :)
@Ultimatereloader are you up Mission Creek?
The 308 Winchester has been underrated for a long time it will suprise you what it can do
Don’t try this at home!!!!
This is a great video on the subject of pressure signs and how they don’t equate to max load/ max pressure. I’ve used book listed velocity as a stopping point for 30 years for this reason.
That said, whether intentional or by accident, this may be the best advertisement for Alpha brass ever created.
Wish Alpha Brass made 22-250, .223, 22 or 17 Hornet brass.
Issue is, modern cartridges like the 308 and many of the most modern are quite straight in the body and that reduces the visible signs of pressure compared to older more "vedge" shaped..
@@jmkhenka The case taper? Yeah, .308 has much less taper than, say, a .22-250. I just found an old .22-250 round in one of my really old rifle cases (must have been my dad's as he had a .22-250) and I was comparing it with .308. First time I remember looking at a .22-250 and it seemed like there was a lot of room to blow the walls out straighter, use a sharper shoulder, and you could probably get a lot better performance... Though you'd probably want to run heavier pills/larger caliber so that it doesn't kill barrels even quicker!
Totally off-topic but as I was comparing the two I was thinking "why doesn't the military use a case this size" as they've been wanting to go back to short-action instead of intermediate. Seems like you could get better velo's creating a round with a COAL between the 5.56 and 7.62 NATO, Like a 2.5-2.6in COAL, with a powder reservoir in the middle of the two. I guess it's probably due to standardization of box magazine sizes and splitting the difference would require an entirely new magazine design.
But yeah, like a ".223 rem mag" or a ".7mm-08 special" , but not just adding/subtracting length, having the case head diameter split the difference as well. Get better velocities, flatter trajectory, longer effective ranges than an intermediate, while saving some weight and having less recoil than with a .243/6.5CM/.308. But maybe people have already tried it and the gains wouldn't warrant the cost of development...
Don't mind me, I'm just thinking to myself, lol
Glad see that you mic'd the case heads. I was so close to commenting mic the case heads in the first minute of the video and huge sigh of relief when you started mic'ing the case head
Lol, glad I read through some comments before I made the same statement.
@@billbennett9537definitely a comment worth making repeatedly. Started carrying my micrometer with me when testing hot ammo
Outstanding! As a long-time fan and user of the 308 Winchester, I am amazed at the results obtained. :)
Any video that says “don’t try this” I can’t click on fast enough 😅
Can't beat a good disclaimer! :)
Yup
I see .308, I see .300 win mag. I click. .30 cal is where the party is at! Super cool work!
Likewise.🫡
@@notyouraveragegoldenpotato Thank you!
No click bait here! Thanks Gavin!!!
most excellent concept and video! Would love to see same concept for 30-06 and 6.5 Creedmoor cases! Bravo!
Excellent video and appreciate the multiple safety warnings. We worked up a 300 H&H full case load with a flat base 150 grain bullet that shot fine in my pre 64 model 70 Winchester. Took one shot in a friend's Remington model 721 and had a stiff bolt opening with brass and primer pressure signs. Much caution required to be safe when pushing loads.
Keep pushing the limits so we can all continue to learn more! Great video, great components, great gear, & great guys.
Thanks, will do!
Absolutely amazing video guys. I’m fairly new to long range precision shooting but I’ve come a long way this past year. I lost my leg while in a coma from Covid 19. So since hunting was so much trouble I dove right in to target shooting, starting with rimfires. I watch your channel pretty often. Y’all take care from South Louisiana.
Mike
Wow, sorry to hear about your leg, and glad that you are finding great ways to enjoy shooting sports, thanks for supporting our channel!
@@Ultimatereloader Hey thanks so much for the reply. I did want to say we got our 1st 1000yard range just last October. I had 8 impacts out of 10 shooting their 6.5 Creedmore. I always would shoot on the pipeline at the camp but our sport of long range precision shooting had yet to take off. I am so happy to see how far it has come in very recent years. Anyways, thank y’all so much for the work y’all put in making videos. I’m sure it’s not as easy as most people think it is. Take care
Good work men.
A cut-away of Alpha brass vs other brands would be a perfect addition to these videos.
Key insights:
1.) Case head pressure signs are depended on the type of primer, brass, and bolt face.
2.) A case failure will most likely ruin your action and could injure you.
3.) With strong brass, case head pressure signs don't appear until you are well over SAAMI levels.
4.) Alpha brass w/ SRP is tough stuff.
I would love to see you test brass life w/ the 44.0 charge (did not show extractor swipe and estimated 80kpsi)
Make wise decisions people....
At the risk of sounding like Captain Obvious here are a few more factors to consider about this exercise:
1.a) Precision reloading equipment, instruments and techniques to match the loaded round as close as possible to a specific action and chamber.
2.a) A high quality action mated to a barrel chambered by a very competent smith. Everything about this rifle and the ammo is TOP QUALITY.
Bottom line: You wouldn't shoot this ammo in any other rifle because this load development is very specific to this one single rifle. Don't try this with a mass produced off-the-shelf rifle that by design has much looser tolerances - that's why we have SAAMI specs.
Ask Scott about his serbu .50 cal accident.
Great video. You took it to the limit with the data and great range shooting.
Thank you!
I would love to see this same video, but with 300 win mag max loads.
Great ammo test and testing long range with the load was cool to see in some beautiful country that is what hunters experience out west. Thanks for sharing this with us.
Thank you for this Video ! Very Interesting I have been reloading mine 308 at 43 grns And thats for me and my rifle sig blazer sweet spot , with a 168grn bullet tack driver for me!
You guys are nuts. Definitely a do not try at home load. I flirt with the max recommended pressures with a lot of my handloads. This is another level. Especially with that bullet mass. Fascinating to watch and a little horrifying the whole way. Truly impressive results.
I'll add to the chorus. DON'T TRY THIS AT HOME!
:)
@@Ultimatereloaderive been testing pure zinc rounds. Still not sure about instant pressure for seating depth/internal space vs the lighter weight of the projectiles fired. Would think a lighter bullet seated at the same depth would exhibit less pressure. I tend to load hot and shallow seat as much as possible anyway. But?
When you deal with tight tolerances, premium consumables, etc this is the result.Intriguing video.
I shot Palma for many years and came to the humorous conclusion that Varget max load in just about any case was fill case to top and crunch the bullet in. If it springs back and pushes the bullet out, you reached max. Barnard action, 31" Krieger 1-10, 47 grains of Varget in a Lapua case, 155 Sierra and 3000fps 308 Win. Varget is the king of powders.
Very cool guys. I love watching two gunsmiths seeing what they can do lol.
Thank you for watching!
No Kentucky Ballistics collab for this one?
Those are good guys over there!
He's got enough holes without needing more
😂
Avoid SLAP rounds
No horrible idea. Do not even let Kentucky see this.
very impressive! and the place you were shooting, that is just beautiful. Sure would love to try it. kool stuff guys!
Very enjoyable, interesting and informative! Thank you.
Glad you enjoyed it!
I load my 300 win mag long. 76gr h1000, Berger 215gr hybrid at 2900 fps.. you guys are nuts for even cracking 2700 in a 308 lol
I compress varget, 195g smk through a ar 10 ,just barely flattens primers
In my rem 5R, I ran 185gr Berger Juggs to almost 2800fps using PP-2000-MR powder. The best load was closer to 2750, and now it has slowed down to under 2700, but still shoots the same. 1400yds on a silhouette is tough, but doable.
Great show
This is honestly now my favorite UR video. Every aspect of it. Layout/presentation, loading, testing, data, and even some long range! Nice first round impact @ 1,300+ Gavin! 6.5 CM with CCI 450's or 6.5 PRC Peterson or Lapua with Mag primers as well, would both be interesting tests. Thanks for sharing a glimpse of the bleeding edge of DNS (do not shoot) performance. Moore 25 Creedmoor, before Hornady announces it!
In the early 90’s Handloader had an article using VV-550 to load the 308 to 30-06 levels. As a new handloader this sounded great. I proceeded to work up to their max charge weight and lo and behold my 20” .308 was achieving 24” 30-06 velocities with 165 gr bullets. Unfortunately the brass no longer retained the spent primers and thus ended my high performance 308 loads. This was either Winchester or Remington brass: I was content to load the 308 as a 308
Ackley would be proud of you guys for this one!
WELL SAID! Too many safety Karen's around here.
AWSOME video focused on safety and performance
Thank you for sharing this great information
Good to hear about bat machine. I hope Bruce and everyone are doing well. Back in the 80s there was a high-power shooter selling steel replacement case heads for 308 or 30 ought 6 cases. They were giving me the same 80,000 PSI pressures that sig is boasting about for their new cartridge.
Alpha Brass cautions reloaders about unreliable pressure signs with it's brass. It is super brass for reasons.
Peterson also. It's in their product descriptions everywhere.
@@randomidiot8142starline has the small primer 308 brass too although i think theirs is the standard flash hole size. Tried lapua brass with the .059 flash hole size and didn’t really notice any hang fire. Not like in a flintlock anyway
As a hand loader this is equal parts scary, funny in a wow sort of way and surprising. Very interesting but I will continue to never go above the listed load data, if you need more power step up to a more powerful cartridge, this video does a good job at illustrating just how fast the pressure increases with every grain added.
I'm perplexed, how does one overpressure a cartridge with a powder that is nearly impossible to overpressure in said cartridge? On top of that, not deforming the ogive or meplat?

phillhuddleston,
I never, well, Almost never, say never... ☆
@@fjb4932 True.
@@PBVader Good point, max loads are usually a slightly compressed load with 168 gr bullets and with as long and heavy of bullets as they are shooting I would think it would be difficult to get that much powder in the case.
Good stuff gentlemen. Thanks!
Thank you for watching!
Those last 2 or 3 test I'd of been pulling the trigger with a string & hiding behind something..that was nuts & even more nuts that it handled it well & you guys still have your faces ..lol..great video guys 👍
Why? The brass will show you everything you need to know long before you need to use a string to pull trigger hiding behind a tree! That along with sticky bolt !
@@user-sp9hy8tq4j And also have realy strong action.
I have done certain experiments I won't detail here, but this confirms my thoughts and observations from results I have gotten. To get more out of a cartridge, the brass needs to be tougher to handle higher pressures. With such brass, cartridges can be more efficient with powder to velocity. Interesting to see if we can redefine the limits of our cartridges with better brass.
308 Gavin improved brass
They are exceeding the yield limit of brass. Their chamber is supporting everything the brass can not flow because they have blocked off all escape routes for the brass. It is not just the brass that is holding it together.
30" barrel, throat to except that bullet pushed way out and a honed chamber to hold that brass better. .000 headspace, that thing will be sing'en!
277 fury is the brass you’re looking for
@@K-bob_45 yep. I've reloaded mine 6-7 times at.. HIGH.. pressure and they're fine.
Living every young handloader's dream!
Alpha Vs. Sig Sauer…. One piece process Vs. 3 piece process.
I believe Sig has it down to a two-piece case now.
Wait what, 3 piece process? I assume you didn't mean the brass isn't made up from 3 individual pieces, right? You're talking about 3 brass forming procedures? Because I always though brass (or aluminium and steel) casings were made from a single piece, first a disc is punched out of a strip of brass, which is then progressively stretched, cut to length and necked?
@@pieterveenders9793 sig fury steel head 80000 psi cases.
@@pieterveenders9793SIG has a hybrid steel + brass case made out of 3 pieces, RUAG Swiss P uses 2 components.
@@GiolliJokerIncorrect. SIG have reduced the case to two pieces. Nominal pressure rating of 80,000 but possible to push over 100,000.
With a high quality action, small firing pin, no ejector, you get pressure signs further. Then you add a longer freebore, a longer barrel and you get a .308mag
32" .308 f-tr build, done.
This is a great video! Love your channel
Thanks for watching, we had fun with this one!
I think you should do 30-06 next
I liked seeing that old Weatherby box on the shelf. I have a few of those floating around too!
Me shooting a 308 and 300 win setup I was setting up my 300 195 eld with 69 grains of h4350 with testing today and this has me stoked to try some new loads with 308. Thanks Gavin for all the intel. Im gonna show this to Ray helms when he gets back from vacation see what he thinks for the mile challenge next month
Varget is a better powder for 308.
Quite a Few years ago, I Bought 500 Rounds of some .300 Win Mag ammo from someone online. The ammo was Factory Loads and the Boxes were the White Cardboard like you can get from Midway with labels that had all of the Load data. The OAL and Powder Charge (IMR 4350) were well over anything I could find in any Reloading Data. So I contacted Federal and asked them if the ammo was safe to use. They told me that the ammo I had was Custom loaded for the US Navy's Long Range Competition and I should NOT shoot them in any Commercial Rifles. So I took the rounds apart and reloaded them to a "Safe" Charge weight and OAL. I still haven't shot any of them yet, LOL!
I’ve done .5 grains more then what my max load was reusing the hornady brass with Cci 250 primers. Then I reversed engineered the original load found out the 195 eld match was 68.4 grains of imr 4350 so with 69 to 70 I’m ok.
@@rodneyferguson446 IMR 4350 burns too fast for the 300 Win.Mag. The best powder I have found is IMR 4831 or RL 22. I use 74 gr. IMR 4831 with a 180 gr. bullet as my standard load for elk hunting and I get sub 3/4" MOA out of my Remmington 700 at 3100 fps.. My Winchester doesn't like the 180 grain bullets, but shoots sub MOA with a 200 grain flat base bullet. I performs best with 73.5 gr. IMR 7828 at 2850 fps. If you shoot a copper bullet or one with a thick copper case (Trophy Bonded) reduce the powder about 2 grains in both examples.
I believe the chambering, the barrel strength, and action strength along with the Alpha brass has to be right or one could be asking for a trip to the hospital or even the morgue. PEOPLE PLEASE BE CAREFUL. Thanks Gavin for a great video and very informative stats.
Before your panties get too wadded up, consider that the same basic receivers are used for .338 lapuas as .300 win mags and .308s. .700" bolt bodies and 2 lugs is very very common. The thrust from a .308 case vs a Lapua case makes the receiver very overbuilt for .308 or marginal for .338 Lapua, but no one gets bent over Lapua loads that are inherently more dangerous.
Pressures are likely to go up to 62000?
Looking at those pressure signs in the brass made my skin crawl! Thank goodness I'm not nearly as adventurous as you people when it comes to reloading!
Incredible to see the maximum potential, of the caliber, no matter how horribly dangerous.
You guys were living the dream I would love to be able to pursue in this video.
I bet the muzzle brake was working good...... I loaded BLC-2 to the max LEE book load with 155gr ELD M. I stuck 2 cases out of 3 & blew out 2 primers.... I felt no recoil. I fell for the brass that said reamed trimmed & ready to load. They sell 308 & 223 brass in plastic jugs won't name them. You sold me on the Alpha Brass. Don't worry I will not try this but great video
Same here with junk hornady brass
What I’d give for everything on that table…preferably that scale gavin…used a lee beam set 4yrs and need to upgrade
E-Bay often has good used beam type scales for good prices, bought one years ago and still a great scale, much faster and easier to use than the Lee scale.
Great video!
Somewhere in that great gun room in the sky, Ken Waters is smiling and nodding his head in approval. :)
For a inside joke should of worn Kentucky ballistics “put a thumb in it” shirt but great info curious on what a standard rem700 action can hold up to now
Let me know! I like mine as it is, don't have the inclination to ruin a good shooting rifle.
Well I just received my first box of alpha .308 brass a couple days ago, but I thank I'll stick to the normal recipes for my freedom seeds thou, I'm not that brave of a spelunker like you fine fellows.
Holy smokes guys! This was incredible but insane at the same time! Awesome to see actual MAX EFFORT 308 loads.
Nerds are awesome. Shoutout to all the fellow nerds doing the cool stuff
This is a great video which highlights what i have heard about small primer pocket brass; you can shoot much hotter loads than with standard large primer pocket brass. I have small primer pocket alpha brass for 25 CM, 6 dasher and small primer pocket lapua for a 308 and small primer pocket for a 6 CM. Have you tested lapua or peterson to over 80k psi? Also when i see many "pet hot loads" on forums, your video proves what i assumed: most of these loads are substantially over 60k psi. Many are likely 65 to 70k but my experience is that most large rifle pocket brass will have loose pockets in 2 to 3 firings with high pressure loads, even with no stiff bolt lift, no extra case expansion at the web and minimal plunger/ejector marks.
I have Gordon's reloading tool on my laptop which is similar to your computer program but mostly i load based on years of knowledge, powder burn rates, good load data, always using a chronograph, watching cases and primers; it's apparent from your test that high quality brass like Alpha, will not show tyoical pressure signs until the load is Waaayyy over max. It seens that loading to 70 to 75k psi with quality small primer pocket brass is "safe" and 60 to 65k psi with large primer brass is safe. For long term primer pocket life in normal brass, 55 to 60k range is probably ideal.
Thank you again for producing quality vids with informative and in depth tests.
Thank you for watching and for sharing from your experience (I need to learn GRT!)
Unfortunately gordon died a couple years ago but his website was still up and i think his wife or a friend was running it. Its pretty impressive but generally i reload based more on experience and trying many variables with my chronograph, calipers, compact rcbs scale, battery pack, arbor press and wilson dies at the range. I do think Gordon's program and the program you use are very useful: they shorten the learning curve and prevent many reloading mistakes.
I run petersons small pocket primer in my .308 ! It’s even better than lapua brass imo
I am using this same brass with my 16" barrelled sig cross in .308. I am shhoting 180 grain sierra gamechangers to 2560 fps. Effortlessly. No pressure signs. No issues. Insane power. Short comact setup. No problems. Pure awesomeness!
Nice results!

Wow, thanks!
@Ultimatereloader I mean it. I don't ever reload max usually end up 1.0 below book. But this video really scratched my itch of wondering what happens with ideal circumstances. I ordered 500 worth of ocd brass after watching this in 6.5 creed with small rifle primer to really stretch out my mpa
Very entertaining, informative, and eye-opening. Not that I will ever try this.
I found the fact that 1 gr = 50 fps very interesting. I've seen this same thing in my testing.
Damn. I was looking at quickload velocity not actual😅😅😅
The videos thumbnail is pretty good 😂
Thank you :)
Absolutely amazing!
Absolutely insane!!! Love it.

This is awesome brass! Ive had problems with .243 with Federal Fusion and signs of over pressured ammo. Nice vid! God Bless.
What a beautiful property!
Thank you!
I always wanted to do that, but I like my face how it is.
Good call!
I run 7mm08 with Varget nosler 140 AB near 7 mag velocities. Super neat round.
If you don't mind sharing, what brass, primer, and barrel length? I just got a Tikka 708. Don't have dies yet but considering it. I found 2 factory ammo that shoot extremely well so I bought 2 cases of each with the same LOT number. I have varget and multiple large rifle primer brands on hand, as well as 140 Nosler bullets

Pretty wild, nìce to know this much more can be done with the right gear and knowhow, and great marksmanship too
Serious question or thought. Could you neck up the .277 Fury hybrid case and be able to use its steel case head to handle more pressure more safely?
Perhaps
Other commenters say sig is making steel head 308
I already did. It's just brass.
Huuuh, if my primer blows out, is that a max charge?
😂! I’ve had one blow out! Fked my bolt up
Thank boys love yall.
Now this is real reloading!
This is when I recommend “getting a bigger boat.”
If you want to push velocity; just get a bigger cartridge.
Cool experiment though!
There is no replacement for displacement, and at the same time, military and civilian cartridges are going more extreme, and this proves that Alpha gives you some much needed "headroom" for those cartridges, and with extreme temps/conditions!
~45gn Varget .308 loads with the berger 208/215 hybrid is not uncommon in F-CLASS FTR competition. I know people getting 3-4 firings out of Lapua brass with loads at and above that. That's generally with a freebore of 0.200"+
This is mag feeding in a .096" freebore chamber.
@@alphamunitions5607 Just sharing first hand experience that pertains to the subject of the video from someone not sponsored by any of the companies involved. The alpha brass I've seen has been very good quality.
Staggering! My initial thoughts were very not flattering towards this excursion. But I am quite surprised. Overall conclusions make sense overall. Thank you.
Thanks for watching! It was pretty crazy to do this test :)
Y’all are mad lads and I’m here for it lol
Theres your Charged Cases..... And you primed them already ?... Who in their right mind would prime a case AFTER charging it lol
Why? Despite the warning, someone will try to blow their face of any way.
people do it anyways on a regular basis
@@SigmaBallisticsthen they should film it and post it on CZcams. I like a good "told you so" story.
I used to take my Weatherby chambered in 30-06 to 300 win mag velocities all of the time. My primers never bulged, my brass never stuck or swelled and I never had any problems of any kind. It also shot my 3100fps 150gr boattails to minute and below groups. It was my favorite Pronghorn and Mule Deer rifle for years.
That scope cam at 23:52 is so cool! You see the bullet and then a perfect center punch on target.
Been usin alpha.308 lg pr awhile and good to see this….i like there ammo bx too
Now this was fascinating! Would love to see other cartridges tested like this. 556, 6.5cm, 7mm, maybe even 338?
Great video …can’t imagine the time you gentleman have invested in this video
In 308, my accuracy load of 44.0 grs. VARGET/Hornady 168 gr. AMAX/ELD-M/Hornady brass/CCI 400. 2700 fps from 26" barrel on a trued Remington action with bushed firing pin. Rifle was built 28 years ago. I need to upgrade my equipment. Excellent video!
Pretty impressive work here. I love SRP 308 brasss. I’ve tested some lapua SRP brass in my 308 win, yielded ~100 fps more than some of my other loads in 150 grain.
However if I was chasing 30 cal speed, I’d go with a 300 WSM. I like the shorter barrel efficiency, especially for suppressed hunting.
Thank you
Very interesting!
I have been using the Alpha brass. In 6.5 CM with 147gr ELDM I have exceeded max with great results. The velocity is 2812 FPS with a 22” bbl.
Very much enjoyed the 308 video. Thank you
Thanks for the data and video Gavin! Very interesting results! Would love to see the combo of 7mm-08 with the 195 EOL bullet to see if they can get to 7mmWin mag velocities..
Great stuff
