Home Forums Hunting & Shooting AR and Tactical Rifles 6mm arc loads

Re-shoot of Berger 88s, on the lands, CCI 400, starline grendel brass, 31.3 grains of Lever. About a .75 inch group.

Re-shoot of hornady 108 elds, max load of Lever, CCI 400, starline 3x grendel brass. About a half inch group.

Starline 3x grendel brass, CCI 400, Berger 95 grain VLD on the lands in a slotted mag. Max load of Lever. Maybe a hair under a half inch.

FINALLY.(grin)

Pass the 108's in real mags. Hint..................

Yep. I might eventually try some Berger 108s, if I catch them on sale somewhere, but I'm in no hurry. The Hornady 108s shoot plenty good in normal mag confines. I think I'm done.

Those 108’s look damned good to me.

Need to get busy with mine. That’s a sweet combo!

The 108s with a max Lever load are cruising along at 2692 fps for me. Not a bad place to be.

Hell yeah, that’s a super load. I’ve got a slew of 105 HPBTs and a decent around of 108’s as well. That’s great stuff. Thanks for all the shooting.

Have fun with it! I'm enjoying mine. One last load to share. I have a few hundred hornady 105 bthps still, and was never really happy with how they shot with anything I had tried so far.

I'm happy enough now. 105 bthps to the lands, CCI 400, starline 1x grendel brass. Shooters World Precision, 27.0 grains. About .8 inches, and shoot to basically the same 100 yard point of impact for me as the 108s with a max load of Lever.

If the speedy powders don't satisfy you with the 105s, try some Varget or Shooters World Precision. I didn't chrono these; I assume they are just loping along, but I bet they wouldn't bounce off anything.

AUK,

Bolt gun or AR?

Gotcha. Thanks Auk. I’ll be trying some of these soon.

He references his build in page 1 of this thread. It’s an AR. I chit canned my 6 ARC.

Why’s that? What happened?

It was ver inconsistent. One day shoot great, next day like chit.. it’s a 18inch faxon barrel with mid length gas system. I had to put a gas block on it that thing just a pain in the ass. Down the roads I might revisit with a way better barrel with a rifle length gas system. Also like stick says find lapua Grendel brass. I have better things to do and chase my ass on that. I bought a 1-6.5 twist Valkyrie barrel it will do what the 6 arc will do with 88 eld-m, with no fuss.

Gotcha. Makes sense to me. Too bad it was such a clunker for you.

I think you may have gotten a Friday barrel and I got a Tuesday barrel. LOL. I'm having decent luck with mine, but yet it was over gassed just like yours. I think it was X-Ring on Youtube that talked about 16" and 18" AR barrels being the best and 20" and over have been very iffy. I think a bolt gun might be where this round shines the best at. I'm to the point, I'm going to run mine as it is and play around with some more lods. I'm not going to get to worked up with several different loads for it though. I did find some 58 gr. VMax's and I have a pound of LT-30 I plan on playing with. I just want to see how fast I can get that combo to go. The only thing I plan on shooting with it though, is a target.

Chronoed my hornady 105 bthp load today at lunch. 27.0 grains of Shooters World Precision gives me 2529 fps and shoots to exactly the same point of impact at 100 yds as my 108 eld load.

Pretty handy. I may just super glue my turrets down.

Has anyone tried 90 grain Nosler Etips out of the ARC? I’m wanting to try some. Got a few boxes of them somewhere. Should be a good hunting bullet.

Im looking to rebarrel an AR to 6 arc. Have any of you fellas tried 65 or 75 vmax, 80 ttsx, 95 lrx, with good results? I'm really interested in what people are coming up with on 80ttsx since I love it in my 243. Also I'm looking towards the faxon 16" match series barrel. I've had good luck with them on a 308 and couple 223 barrels. I'm not stuck on the faxon. Just wanting to stay as light as I can so no longer than 18". If you guys have better recommendation I'm all ears.

I tried some 87 vmax in mine but never fooled with them much, as the 88 Bergers showed more promise in my particular barrel. Didn't try anything lighter.
