Alliant Reloder TS 15.5 - 308 Win and 6 ARC

I do the same. LIKE even before he starts. He should have a LIKE for every single VEIW

[@Toolness1]

@@RMM--uv7uk It never occurred to me, but a lot of people don't ever like or dislike vids (not that dislike means much these days unless you have the chrome app). They just don't get that it helps the creator and is a small way of paying them back for the effort that was put into making the free content you are being provided. I tried explaining it to a couple people recently to try to get them in the habit of liking vids especially for smaller channels and the two people I was speaking to looked at me like I dropped off the moon and continued on with their zero feedback YT existence, immediately disregarding what I told them. It kind of pissed me off to be honest. I guess neither of them have a clue how much work goes into making and editing the vids they enjoy.

[@texasrex2222]

That fly had some brass balls, hanging out on the target without even flinching as a round passed right next to it. In all honesty though, it was cool to see a point of reference for size of the group. Knowing the numbers is always what I watch for, but it was interesting seeing something in the frame to visualize how tight those groups were. Great shooting!

Johnny its been 3 years now since I started loading and since I started watching you. Thank you for helping us NOT blow out faces off! I'm now loading for my Bergara in 308, my bar 270, 556, pistols, and of course.... My 5 300 blackouts!! I'm now dialing group in down to .2-.3 regularly! I now have my 300 blk mule deer load for this year. Ruger ranch 120 barnes, lil gun, and 2600 fps!! Thanks again for all you do man! Also watching you made me a horder of supplies. I was ahead of the curve on the coof coof and I just kept buying and buying when I could. I'm now not gonna run out of primers lol. One more thing, check this out. We always see weird stuff in hand loading right? My most reliable and repeatable 308 load is (3001 fps SD 7.1)150 Hornady Interlock soft point, 50.2g of cfe223, CCI Br2, with AGUILA brass!! 😂 😂 Freaking Aguila brass I don't get it but it works!!!

[@rootjr.3658]

Care to elaborate how you are getting 2600 fps out of a 16" barrel, .300 Blk with that 120gr Barnes, or is that a typo?

[@ron4hunting]

when alliant said they were coming out with 15.5 and it being slower i thought they had started reselling a old surplus power called 'data powder ' . why back when they where here in tn . yea that long ago . i went in with a 5 gallon bucket and got 4 pounds of it . only the owner filled the bucket to the brim with it and charged me for 4 pounds ! still got about 6 pounds left . is was a great powder in 223 and they still show data for it . figured 15.5 would get me some fresh powder . wrong one look at the grains you showed said nope . 'data powder ' is a ball powder . thanks you saved me a bunch of money ! great job .

[@reaford2004]

I’ve never seen the 6arc brass I’ve made from Grendel act like that. That was some crazy looking brass

[@5napperlicious]

Go over pressure and you'll see it. I had the same thing happen with some Lapua and Starline 6.5 Grendel brass that I resized for 6 arc. The cases are thicker than the Hornady, so I ended up over pressure and the cases looked just like that although no bent rims.

[@quentinjohannes8396]

There’s no way I wouldn’t have changed the game to “shooting a flies ass” when it was hanging out by the bullseye. Only the best shooters can say they can hit that!

[@sethbutler4393]

Should have tried shooting the sprinkles! Lmao

[@bchecker6307]

There are targets called fly paper, with a bunch of flies on them,...great fun competition.

[@chrisw2907]

I just jammed as much as I possibly could in there it was just over 29 with the 105 amaxs. It was pretty good but didn't have a chrono so I'm happy you made this video. So I can figure that out. But I did find the accuracy of 15.5 more accurate than 15. Haven't watched a video of yours in a while glad your still making them. Wish primers and all that stuff would come back.

[@chrisw2907]

I will have to check again if it was 29gns been a while. But I didn't have any out of the ordinary pressure. Maybe it was lower. But that ring on the bottom does happen dude. I tried multiple sets of sizing dies to get rid of it. But I found that believe it or not the lee sizing die worked best for me. And that was with 6.5 Grendel Lapua brass. I need to start reloading again been a long time. Thank you again for the video man. Just got my 6-24 Midas Tac HD mounted on my 6 ARC last summer so i can't wait to actually use it. A 10x scope just doesn't belong on a 6mm ARC. Thanks man

[@ramsaycountry1177]

Never heard of a "belted" 6 arc!! Lol

[@salg7998]

I'm glad you brought your target cam back. Keep up the good work

[@dahut3614]

2:57 My Hornady 6ARC die set 546251 came with that seating stem, so I didn't find it necessary to buy another!

[@IWatchedWhat]

Friday. Have not seen that with any I made from 7.62x39 or my Grendel brass, but some guys have reported stuff like that on the 6ARC forum, but can't remember what powder they were using.

[@number40Fan]

You have to cut these cases (as well as the 7.62 from the resizing video) in half now. We gotta see what is going on in there. I'd be willing to mill them in half for you, if you like.

[@lunkydog]

I get that the shot marker doesn't necessarily line up with the target dot, but the comparison between the groups @9:17 shows a difference in group shape bullet to bullet wise. Just pointing it out.

[@ewetho]

I approve of this use of 200.20x this is exciting

[@williambell7763]

Looks like you got the grendel belted magnum, just overpressure from what I have read, found a post on snipershide where someone had basically the same problem, brother had it happen with remington 6.5 grendel factory ammo.

[@williambell7763]

Reading further may be mitigated by turning gas down, idk though may take some playing around with

[@williambell7763]

Post 7 on that link says its a function of the overgassing, maybe the slow powder is giving higher port pressures, and forcibly overgassing an otherwise good setting. Maybe try again with the gas shut off, and a string to pull the trigger.

[@williambell7763]

Hmm, link won't post, Google snipershide grendel belted magnum, should be the fist link, guy made the post this year so should come up

[@guardianminifarm8005]

Appreciate the experience & data. Rough 6 arc brass. That is concerning. Look forward to temp stability test.

[@upnorthreloading2214]

Ohey! There's load data for 7x57 Mauser; max charge of 41.6gr to achieve ~2750fps for a 140gr pill. Those numbers basically translate out to right on par with the other "sweet spot" medium-burn-rate powders. Hopefully, someday soon, I'll get to see how things it makes things print on paper. Thanks for the vid!

[@jamespugh]

Great video jrb have keep look out see how keeps performing in long run . Vargat is well used for everyone

[@CorwinBos]

Good stuff man! You should be able to hold the Berger 185 Jugs to mag length in your AR10. They are a fantastic 100% capable 1000 yard bullet that aren't terribly jump sensitive and might run a lil better with that 11 twist Krieger. Ive made some belted cases on my 6 Grendel too. A heavy charge of H4895 and a 105 Berger did me in. And no, thats not normal.

[@AC-bl1rl]

Love my juggs, haven't run them in my 10 yet, but have gone 1400 in my 5R bolt action.

[@Mrjaspgu]

I just picked up 12lbs of 15.5 would love to see a grendel video and further 15.5 videos!

[@rootjr.3658]

I would think that one of two things are happening with the 6 ARC brass. either you have a recess milled at the rear of your chamber, or your dwell time is off causing the bolt is starting opening before pressures have dropped back down to a safe level.

[@rodneydavis8110]

Hi Johnny I have made 6arc from starline 6.5 grendel with Hornady dies and it looks like new brass thank you for your videos

[@AnthonysOutdoors]

Exactly why I have never been a fan of forming brass from other cartridges. I'd throw everyone of those away and start over once you get some fresh ARC brass.

[@RatelLaw]

Thank you for sharing your research.

[@thereloaderscloset9096]

When my 300 showed some issues like those but a faint line, the cases were about to separate. I had one that did separate which gave me a little rod work to get it out. Be careful.. The side wall is getting really thin. Cut a good one apart and one of the other and measure with a ball mic and see if there is a definite thickness difference.

[@userJohnSmith]

I would encourage serious caution on the load data on the ARC. I just had an overpressure failure while being within the load data limits and had sudden pressure signs.

[@jayel6608]

I've had Starline Grendel brass make a similar line just from sizing, tried 3 dies, adjusted lube amount and variety same deal.

[@dahut3614]

QuickLOAD predicted for 18" barrel with RL15.5, 108 grain ELD-M, and 2.260" OAL: 27.4 gr. 56082 psi 2544 fps 27.8 gr. 58813 psi 2580 fps 28.2 gr. 61685 psi 2617 fps 28.6 gr. 64705 psi 2652 fps Not _too_ far off with the velocities, so I imagine pressures are in the ballpark, Johnny Bench! Case volume was left at the default of 34.5 grains H2O.

[@aaron.from.winchester6744]

I wouldn’t want my face behind some of those pressures in an AR.

Can you do a comparison video between AR Comp and 15.5 TS in the 6 ARC? Really looking for the perfect stick powder to use on my rifle.

[@DanielBoone337]

If it'll shoot the heavies in 308 I wonder what it'll do in 6.5 Creedmoor I'm assuming it might be a little fast but I've never used RL 15 or 16 before... I'm always happy when new powders/bullets come out or I find another one in stock that I've never tried before just because it gives me something new to tinker with I'm one of those people who can't leave things alone... LOL I can have a load worked up that I can drive tacks with but I'll just load up a few rounds to have on hand then immediately start changing things within that load or switching components to see if I can get anything else out of a cartridge. Great video as always keepem coming brother!!!

[@perrytilton5221]

I've had issues like that with my Starline 6.5 Grendel brass except I see that much earlier on in my testing. Anything with the webbing area greater than 0.439" it's trashed and not sizable. You're lucky to the case didn't stick in the chamber. I've had a case look like your last charge and the case stuck in my chamber. It did prove that the JP HP bolt and extractor worked flawlessly because I had to kickstart the charging handle to get the case out.

[@rustynut1967]

Are you resizing with a Hornady die?

[@perrytilton5221]

@@rustynut1967 I've used both Hornady and RCBS TC/AR dies and both did it equally as bad when above 0.439". I haven't had issues with using either Hornady 6.5 Grendel or Winchester x39 brass. I think Starline virgin formed brass has more case capacity compared to Hornady fired brass. I think JRB and Eagle Eye brought this up as well.

[@davidfosland2236]

I'm looking at trying this stuff in a 204 Ruger bolt and a 17 Remington AR with 24" bull barrel, really hoping it does well. Thanks for putting up some info regarding this newer powder.

[@Drivapete]

Didnt know there was a RL 15.5, Havent seen any powders on any shelves lately. All the powders are selling online for triple price and then some. Seems like only the price gougers are the only ones with any components. I'm sure glad I stocked up before this latest crisis, happy I dont have to rely on these pimps!!

[@bnicedanicest6288]

I had .223/5.56 brass resize like that before. I had a Ruger 556 I sent the upper back to Ruger they replaced because I did have a case head separation the bolt would close on a 5.56 nato no-go gauge checking after the incident. So the brass fired from that particular rifle after resizing would look exactly like your brass the chamber was oversized allowing the brass to stretch to much after it would never resize and fit in a cartridge gauge and would get stuck if I tried to chamber that particular piece of brass in a different rifle. (When this incident occurred was before I started reloading and was factory 5.56 ammo it is having become a more experienced reloader and having built a few AR’s and working on gas/buffer system issues Particularly a LR-308 .22-.250rem/.224 valkery +2 w/ low mass OS after the fact that helped me understand all the interrelationships STILL after all that idk just my 2 cents if you fire formed in that particular chamber your could be possibly oversized circumference wise not length wise and possibly not close on a no-go giving you a false feedback hope this helps or keeps anyone from getting hurt as just one possibility great video as always thx JRB safe hunting and shooting to all

[@rwhipple73]

I'm going to do some testing in 6BR with RL 15.5 hopefully tomorrow. 109 Berger Hybrid and I'm going to try 29, 29.5, 30, 30.2, 30.5, 30.7 grains. My current Varget load is 30.5 and what I've read says RL 15.5 should be your Varget load +.2 grains. Guess well see how she behaves.

[@user-nu8qm7cm5x]

It looks like the RL 15.5 in the 6mmARC might more ideal for a hunting load such as the 90g ELDX. I plan to give it a try.

[@EagleEyeShooting]

The Hornady reloading die for 6 ARC oversizes the cases and consistently seen that FL die fl size and convert brass into a 6 ARC (belted mini mag)..... IMO and experience and surprise. The Hornady 6 ARC die set is not good. Highly recommend looking into getting the Mighty Armory Gold Medal die for 6 ARC else I can make one for you

[@Toona79]

I’ve had the exact same experience with my Hornady die. Have a Lee, that doesn’t do it but it leaves fine scratches?? Time to try again I guess, 3rd times a charm 🤞

[@rustynut1967]

I think your right, it "squeezes" it back down a little to far, but it's still within a half to one thou. of new size. I wonder if it's also that the finish on the inside of the die dragging and squeezing out or bunching up the brass (the band appears to start right at the bevel in the die). The strange thing is I got the band on some 6.5 Grendel Lapua brass resized to 6 ARC but not on Hornady 6 ARC brass that been fired and resized 5 times. Thanks for the tip on the Might Armory die! I have their decapping die and just ordered the resizing die.

[@Anon585]

Finally another 6 ARS!

[@MrBoostin18]

Yessssss thank you for this.

[@SDMacMan]

Hey Shannon. My guess on the 6ARC brass is that the powder is too slow burning, and is still creating pressure when your AR is in the process of ejecting. I bet you wouldn't get that on a bolt action rifle.

[@tyler6147]

I've formed around a few hundred 6 ARC cases (so far) out of Starline 6.5 Grendel brass. I used a Mighty Armory sizing die and I've never seen brass like that at all.

[@DummyRound]

Did you get the lady bug out of the 6 ARC box?

[@TexanUSMC8089]

I don't have a 6 ARC yet, but I've had a 6 Predator for a few years, which is almost the same thing. I necked down 6.5 Grendel brass. After hundreds of rounds fired, I've never seen a belt develop. That's really weird. Looks like maybe the chamber was reamed with it? Maybe you can send a few pics to the barrel manufacturer and see what they say, or just get them to watch your video.

[@John_Redcorn_]

In my experience, RL 15 is really approaching the limit on the slower powder side for ARs, and if 15.5 is even slower then its a no-go.

[@wilhelmvo6399]

The barrel heat as you go through ammunition it will open some and grouping will be off shoot all with a cold barrel

[@dandaly7305]

I was thinking shooting four at the normal (fairly fast) speed, then chamber the fifth for 30 secs, take it out and take the temperature change with an IR thermometer. I think it will be fairly warm in comparison to when it goes in.

[@gunsmoke7193]

JRB I left you a comment on the 15.5 video over on patreon about the belt on your 6arc brass, there's a link there that might be worth looking at.

[@andy347495]

I still use the 185 juggernauts so I cant talk from complete experience, but from the conversations I've had with othert f-class shooters I know; with a 30'' barrel and freebores of .170 the accuracy node is at about 2630 fps. obviously the longer freebore is allowing them to use more powder, which is a little bit more than what you went to. Also, from those conversations it sounds like the 200.20x is a little harder to tune and get exceptional accuracy compared to other target bullets.

[@bubbanater1984]

This is the same death ring I’m seeing on all my 6.5gren to 6mm arc. I’ve been chasing this try and size on it should be even worse after sizing. I’ve been commenting on all the arc videos trying to see if you have the same issues looks like you do. I even get case body cracks on the third firing. I bought 3 boxes of factory ammo just for the brass it doesn’t do it on factory brass. I would love to use 6.5 grend brass but it’s a waste of money. Brass life is junk. I originally thought it was due to the rcbs sb die but after ordering a Hornady die it does the same thing on the grendal brass.

[@tyler6147]

I use a Mighty Armory 6 ARC die and I anneal all the cases prior to forming them. I don't have that ring at all.

[@bubbanater1984]

@@tyler6147 I anneal before forming as well maybe it’s the die I’m using idk or maybe even the chamber it’s fired in allowing it to swell at the base more idk. But seeing this same ring on Johnnys brass makes me thing it’s something to do with the starline 6.5 Grendel brass as I use it as well.

@@bubbanater1984 I don't know what is causing this. My Mighty Armory die however is AWESOME. It will be interesting to see the reasons this is happening.

[@bubbanater1984]

@@tyler6147 I contacted the barrel manufacturer and returned the barrel they said it was within spec and didn’t have an answer for me. Had to send my bolt in as well I just know that it doesn’t have a ring after 7 firings on factory arc brass but it does on grendal brass. The barrel manufacturer Shaw says that 6.5 Grendel and 6mm arc are not the exact same dimensions. There are small differences in the case body and that the case can be stretching reward instead of the neck stretching as it should. So you are pushing brass down to the case head. I’m not sure about that sounds fishing to me. I do know that I am getting case body splits as well not the kneck splitting but the body of the case cracking out after a couple of firing nothing like I’ve ever seen before. And I’ve gotten should junction splits as well. I just bought factory ammo running that brass for now until hornday release there new brass for sale.

I've never seen my 6 ARC brass (made from 6.5 Grendel brass) look anything like yours. That's some really weird stuff you got going on there. I don't know if I'd choose to explore why it was doing that, or just stay away from that load altogether.

[@5napperlicious]

We already know the cause, it's over pressure. The Grendel and 6 arc case seat further down into the bolt than other cartridges leaving more of the case unsupported by the chamber. When you are over pressure the base of the case stretches like that.
