    Thinking of 6mm Creedmoor build

    I have two 6 Creedmoor builds. One has a JP barrel on an Aero receiver set and the other is a Bartlein from Craddock on a Mega Maten receiver set. Both use JP HP bolts, Superlative Arms adjustable gas blocks, and H3 buffers in 7 3/4 extensions. The Bartlein is 20” and plus 1” gas. The JP is 22”...

    1 piece mount suggestions?

    I use a Bobro on a Vortex 1-8. I normally use Badger Ordnance on everything else and have a Seekonk torque wrench. I decided to try a JP mount and installed one yesterday. I’ve only fired enough to get a good zero but so far, I like it.

    AR 308 magazine maximum COAL

    Any time I need to load longer than 2.80, I use KAC magazines. I bought a single ASC but could not get even close to the advertised OAL.

    .243 Gas Gun?

    However, I also have two 6 Creedmoor uppers. This one a 22” JP barrel and matches velocity with exactly one less grain of H4350 than the 243. The other one is a 20” Bartlein from Craddock.

    .243 Gas Gun?

    I hate to contradict the experts around here but I just finished building this 243 two weekends ago. I do not shoot factory ammo but have loaded 87 VMAX, 90 Scenars, 105 BTHP. I ran across a deal I couldn’t refuse on a Seekins Precision fluted barrel and this is the result. I’d say 243...

    Help me find an AR10 receiver set

    I bought a KAC PCC this summer and had a local gun shop order an LMT MARS-H lower directly from LMT. It also fit my Mega Maten but was extremely tight at the rear take down pin.

    Is an 8-inch 308 or 12-inch 6.5Cr build possible? Accurate out to 500 yards?

    Just build them and do range reports. I doubt very seriously anyone has built an 8” 308 around here. I have built a 12.5” 308 and I can assure you it’s NOT as soft shooting as a 300 Blackout!!! ?

    Heavier AR-10 Buffer: Would It Help?

    Immediate question that comes to mind is, what weight “stock” buffer are you currently using?

    He said he wanted to use Berger 105 Hybrids but it wouldn’t feed them so he pulled it and went to a Proof.

    Cheap JP 6 Creedmoor Build

    Lastly, 105 BTHP 40.6 H4350 CCI 200 New, unfired Hornady brass. I’m just shooting steel and using a 1-8 Vortex until I get glass more fitting but I’m pretty pleased for a FREE barrel.

    Cheap JP 6 Creedmoor Build

    I worked up the 105 BTHP from 40 grains up to 40.8 grains. It showed slight ejector marks and didn’t gain any velocity over 40.6 grains.
