Johnny, as far as using J.B. in the throat of the chamber, what John is talking about is the roughness that is produced there from repeated firings, it will start to look like cement patched potholes in that area under a bore scope. There is a school of thought as far as using J.B., That product won't harm your barrel, what it does do is remove all the copper fouling, Your cut in the barrel will collect copper and some say that is a bad thing, But what that copper does do is fill all the small voids and makes the barrel a consistent surface for the bullet to pass through making everything smoother. I use 1/2 Kroil and 1/2 Hoppies mix for my barrel's as a cleaning solvent. Btw off subject, The K-31, Have you thought about getting some newer sights for it in a target type? I think you will find that the rifle will surprise you in accuracy and move to one of your best shooters. they are not that picky about powders in the burn rate of IMR 4895 through 4320. I am very pleased with mine and it will never be for sale. Dave.
I have done several loadings with Vihtavuori and have always been very pleased with it. It is very easy to measure with both with my Perfect powder loader and my trickler. And, as you found, the performance has always been very consistent. Good stuff no doubt. Whether it is worth the extra money depends on what your doing and how much money you have, I guess.
I use a lot of winchester 748 in .223 with wsr primers and get great results. 24.5 grains of powder. Useing 55 grain Sierra and Hormandy bullets. In a 1&9 twist barrel.
Sometimes the extractor can bend the lip of the rim of the case trying to extract a case in a dirty gun. It's easy to check for the just sit a case on a flat surface or eye ball them
I have found that although you can push the 55gr bullets faster, they tend to shoot best for me around that 3000 fps range (at least in my 1:7 WOA barrel).
Great shooting JRB, the eyeball test definitely looks like the Magneto speed chronograph hurt accuracy a touch. Still shot great though. I have that same Forster ultra micrometer seating die that I use on my Redding T-7 and I get the same exact marks on my bullets. 69 and 77 grain SMK's don't seem to leave marks as bad as the 55 grain bullets. I have polished the inside of mine with steel wool that I wrapped around a .22 brass brush and then coated it with Flitz, I then chucked it up in a cordless drill and polished the inside of the die. The marks are definitely caused from the feed ramp area of the die, I called Forster and they said I could send it in, but the inside of that die is .224 diameter so it's tight with some bullets. I also chucked a 69 grain Sierra match king in the drill and coated it with Flitz to polish the inside of the seater stem to help with the ring it was also leaving on some bullets. After all the polishing it seemed to help some, but depending on the bullet I still get some scuff marks. It has not affected accuracy any so I decided to not send my die in. Hope this helps.
JRB - Nice video - you've got a good shooting rig with that good varmint Sierra slug and Vv powder...!! Win 748 fans don't have to get all excited even though their favorite powder took a beating in this video...happens - that's why we test. Been using Sierra bullets ever since day one of my reloading....gone through the ground squirrel fields of Williams and Weed, CA, and the High Power Competitions using the 69 gr and 168 gr JHPBT MatchKings (SMKs) as my bullets of choice. Great work on this channel of yours - always fun to drop in and see whatchagotgoin'... FC Steve
This is my WOA 18" complete upper free floating varmint barrel fluted 1 in 7" twist attached to a Colt M-4 with a Geissele SSA-E trigger. Using reloaded Sierra 69 grain Match King bullets it shoots 3/8" five shot groups at 100 yards. I also have a Bushnell 4.5-18x40mm scope with Custom Turret label accurate out to 900 yards. The rings are 1" high QD aluminum. The group in the picture was with 65 grain Sierra Game kings which I use for deer..The 65 grain Sierra Game kings will shoot 10 shots inside of a dime if I am careful.
I really love your vids and the hard work you put into making them, you know what you are after so with respect to you I will not offer any opinions, I wish someone would grasp the nettle and do the same with a bolt action hunting rifle, very absorbing viewing and thank you.
Glad to see that vinyl back there! Looks like it fit just right! I may have to get myself a White Oak barrel seeing all these kick ass groups it's a serious possibility for my AR
Hey Johnny! Some fancy shooten! I hope you don't start complaining when your groups open over a quarter inch! : ) Nice Barrel, nice bullets.. looking forward to seeing the blitzkings paired with another powder.. it would be nice if you have load data with the Vv....Looking good
Try this one ,case length is 1.750.oal is 2.200 " 25 g of 2206h adi powder ,CCI small primers ,Sierra super roo 55 g spbt,projectiles ,I've been using these in my tikka 223 spot lighting at about the 300mt mark ,awesome..
I would like to try the Wylde chamber out. It seems to really produce the velocity. I shoot 55's out of an 18 inch barrel and a 24 incher. My load for both is 26.2 grains of 748. The 18 incher delivers 2875 fps and the 24 inch barrel averages just over 3000fps. Both drastically slower than that fast barrel you have!
Try using a better primer IMO, the CCI 41 is a mil-spec primer that has a magnum priming charge. Give the Winchester Small Rifle or the Federal Small Rifle a try and see how the groups do. I've never seen the CCI mil-spec primers do well in accuracy, just look at the benchrest shooters and you will see what primers do best for groups :) As for the powders, 748 is a great powder for BULK 223 loads (FMJ range loads etc) but the Vihtavuori powders are the king of the hill for the accuracy world.
William Kister 3-gun match shooters sure. But ACCURACY match shooters (benchrest, PRS, NRL, etc) do not use them, the CCI primers have always had issues with inconsistency in velocity and accuracy. Even the factory made black hills MK262 ammo uses the OEM Remington 7-1/2 BR primer...... not a CCI!
@@jimhans1 Negative, the CCI 450 is a primer many Benchrest shooters. My 6mm BR gets some of the smallest extreme spreads with them, especially with the slower powders for the job.
William Kister now go try a decent primer and see what happens :) Every gun is different, every reloader is different, occasionally there will be the random load that CCI 450 might do better, but not usually. What I said prior still applies, the vast, vast majority of top shooters in the precision rifle world do NOT use any CCI primers, and for good reason.
Very interesting video. Glad to see your magnetospeed comparison. Bring on the Pitchforks from the folks that don't have one! I just bought a Forster seating die for my 6.5 creedmoor. Hoping it helps a little. It sure looks nice. Have you ever done a run out test comparing any of your dies in various calibers? I picked it over the Redding on cost but also Redding claims to tell you that compressed loads void your warranty?
The seating stem is pretty thin near the edges. I have noticed in my 300blk die that seating a bunch of heavily compressed loads will bend it out a little. When it gets spread/bent out the fit to the sliding "chamber" will get very tight and sometimes stick. What I have to do every once in a while is pull out the seating stem, chuck it in a drill, and polish it down just a little with some steel wool. If you don't have the die in your hands yet that probably doesn't make any sense. It's not a huge deal. I think I've done it twice with my 300blk die...so it doesn't become a problem very often. I assume that Redding uses a similar seating stem and has the same problem.
Another awesome video on reloading you do such a great job how about doing Hornady 73 grain Eld 223 I hear it's supposed to be an awesome bullet would like to know your thoughts on the 73 grain Eld thank you and have a great day
Johnny when you changed bullet weight, you added a variable, so you should rezeroed your scope for the 55 Gr Blitakings, because that is a 20.28 % decrease in bullet weight
If this is the final load he's sticking with, then yes, i agree. But for groups it's not necessary, doesn't matter where the crosshairs are. Shooting for groups only...
Ever think about doing a review on the new sig sauer brass? Saw some at cabelas yesterday, and first thoughts I was impressed. The flash holes appeared to be uniform and brass was already annealed.
....just reloaded some 55grn BK's with N133 for my 22" 1:9 bolt, I started much lower with 22.9gr as max load but it was the best with a 1/2" group. According to VV, the 24.2grn is the "accuracy" charge for 55grn bullets with N133 but it seems too hot to me?!
Great stuff Johnny I don't know why I ever switched from Sierra to Hornady Hornady performance ain't near as good as the Sierra, I like your stencil in the background that is cool
One video I haven't seen you try is bumping the shoulder using die sizing bushings and/or competitive shellholder sets. I'm not sure if these tools are for enthusiasts or for lunatics.
I find poly tip bullets usually have some variance in ORL. You chose not to crimp. I assume this is due to having a compressed load? if uncompressed do you crimp (gas gun only)?
I love VV powders. I am slowly shifting to it in all calibers. Have not tried it on 5.56 yet and want to build a nice load for my spr using Sierra 77gr SMK-C in a Noveske 18in barrel. Sierra calls 23.5 gr of N140 and 77SMK-C their "Accuracy Load" Have not tried it yet but looking forward to it. Have you tried any 77 gr SMK-C's yet in any of your videos?
No, but I'm planning to buy some soon. Once the Bobs' bullets get old I am going to buy some of the Black Hills ammo and to a series on cloning its performance. Someone suggested it in yesterday's video (i think) and it sounded like a good idea to me. It's hard to complain about VV cost when it comes through every time in performance. I am pretty amazed, really...I just started trying them in the last few months.
I’m still a little wet behind the ears, but why not measure cartridge base to ogive with a comparator? Isn’t there always small differences in the tips of the bullets?
Maybe I missed something? Title of the video is Butt Kickin' 5.56 Bullets, but you're using Fed 223 brass? I'm looking for info on loading for 5.56 specifically, using either Win, IMI, or LC brass. I have a couple of thousand Fed 223 brass, military crimp and all, but would love to try and load some 5.56. Thoughts?
Forgive me for going OT here, but have you ever tried Nosler CCs? On many forums you hear people rating them as good as berger or SMKs, but for some reason i rarely see any proof of that
Hello Johnny , i know it’s been a while since this was posted but is it just me but seems like the one off shots that go a little off ,the case ejects further back than the rest of the group. Btw awesome shooting....
You can get 400 rounds with this bullet at Global Ordinance for 192.00 bucks right now. You think this round can kill a wild hog? Australia Outback ammo company loads it in this bullet, they say it has 3200 fps. If you want it Global Ordinance has it.
The lesson I got from this, other than this channel is a lot of fun, is that I will never, ever, ever, ever ever buy that chrony he used. I think he said it best when he said..."influences of the chronograph" . And this means its manipulating bullet flight. Too many questions.

I have the same barrel and it loves Sierra 77 gr HPBT and Varget 24.5 gr. Keep up the great videos.
Atta boy Johnny. Good stuff as always - fine data taking and analysis. Keep up the good work.

I’ve been stuffing in 27 grain leaves the perfect little start of a crater. In a old psa m4 that was in a burned down house! Has a fn barrel though!
Sometimes the extractor can bend the lip of the rim of the case trying to extract a case in a dirty gun. It's easy to check for the just sit a case on a flat surface or eye ball them
You always say the brass looks good, could you do a video on what brass should and should not look like?
I have found that although you can push the 55gr bullets faster, they tend to shoot best for me around that 3000 fps range (at least in my 1:7 WOA barrel).
I think the lesson here is to not buy mediocre barrels
A fine example of why handloading is the way to go to fine tune accuracy and performance.
That mosquito at 14:29 was very persistent.
Great shooting JRB, the eyeball test definitely looks like the Magneto speed chronograph hurt accuracy a touch. Still shot great though.

I’ve noticed that if the brass isn’t all trimmed the same length, the o.a.l is a bit different on some rounds.
How do you work that out...the seating die when set will not alter overall seated length weather you trim the brass or not😉

Hey man! Idk what your setup is right now but I think you would LOVE a JARD set trigger in that rifle!!!
Is butt kickin 308 bullets a possible new series you could make??

Great stuff Johnny I don't know why I ever switched from Sierra to Hornady Hornady performance ain't near as good as the Sierra, I like your stencil in the background that is cool
remember the chrono will effect the groups, run with the flat spot in the velocity
Why are you measuring the bullet with the tip and not a ogive comparator?
I am loading the 55gr blitzking with 26gr of A2520 at 2.215 COL
Have you reloaded these 55gr Blitzkings with A 2520

You should compare already made Ammo vs your Ammo

Thats odd. Do you think the chrono being that close to the bullet could cause the down shift?
Could you have done those same loads with N133 in 223 cases?
Forgive me for going OT here, but have you ever tried Nosler CCs?
On many forums you hear people rating them as good as berger or SMKs, but for some reason i rarely see any proof of that
