AR-Stoner 6.5 Grendel barrel short chambered.

[BjornF16]

To confirm. It is on more than just these barrels.

I just measured my Satern cut rifle barrel with hornady brass/123gr amax my OAL to the lands is 2.230.

I'm getting 1/2moa accuracy with Factory ammo that is loaded at 2.245 OAL...

So if i'm jamming 15thou into the lands whatever. 1/2 moa was my goal and I got there with factory ammo in a gas gun. Note--I have no problems with extracting chambered live rounds but did see rifling scores on the jacket.

My feeling at this point and having already sent this barrel back once to get the extension fixed is.... Why "fix" what isn't broke.

Does this **** with my reloading? Yes...now all my loads with 8208XBR will be compressed and jammed into the lands. **** it.

Doesn't necessarily mean you are .015" "into the lands"...you may be getting resistance from the throat, depending upon how hard you are pushing the bullet out of the OAL gauge...if you don't have any problems extracting these rounds then I doubt you are really .015" into the lands.
