My 1 x fired brass shoulder datum has grown .003" in 90 rounds on this replacement Rainier UM.
I actually noticed mine with my eye balls. On the second barrel I pulled it to check for the same problem after 15 rounds because they acted like the problem was with me and a one off problem. Had I been measuring my brass instead of sizing and shooting based on initial set up. I would have noticed sooner on the first barrel.
my 6ARC RTR shipped 12 calendar days after ordering. I did specify cerakote finish, so that's expected, they said 1-4 weeks for that, got it a couple days ago. I didn't specify anything else, like fluting, headspacing, etc.
I received an 18” I ordered to assemble an upper for my son in less than a week. 5 days I think. Shoots great with the factory 108s. He had hits on the 1200 in wind. But I ordered the bolt/bcg and gas with it.

I would'nt even consider it in a BG ..
Probably have 20 rounds on paper and this was the first one for me. I guess what made me second guess is if that had been on a yote at 250y I may have missed.
Where did you learn/hear about that? Any idea what type of projectile and weight?
One of the reps from AAC posted it on another forum. Not surprising since they just did a run of 6.5 Grendel
Personally, I'd put them 20 thou off the lands and load up 5 each of 29.1, 29.3, and 29.5 gr of LVR. I've had several different bullets like a LVR charge in that range.
I agree with that advice. Every load I have and the loads of some buddies of mine all fall in that range with similar weight projectiles (103-109g)
Nice looking setup! There’s some good loads over in another 6ARC thread you’ve probably seen. A lot of my guns love VMAX. Some of the most accurate bullets I’ve shot. They’re often lighter for the load though. 60 gr in .223 and 57 gr in 6 ARC but incredibly accurate. A2230 in 6 ARC is 3500 fps from 18”
Didn’t have any lever laying around but I had some staball match. Loaded up 26.8 and sent 50 of em down range, 2550 fps sd of 12 out of my Odin barrel. Groups were alright. 3-4 rounds would be touching and then a random flier but they were sub moa at 109y. This was two seperate 5 shot groups.
Did all of that 2times
That is unfortunate, mine doesn't have that issue luckily. I would just send it in and see if they can fix it, I had dimpled my barrel and ODINworks still opened my gas port and checked the headspace and fixed my barrel when it was belting every case and not cycling. I am not sure if yours is an odin but its worth a shot. I have about 350 down the tube since I got it back and it is shooting great with the 105/106/108gr bullets. ELDVT is still giving me some random problems.
