So has anyone managed to shoot some groups with these barrels yet?
I did a quick sight in. 1"-1.5" at 50 yards using iron sights and 55gr reloads. Some groups might have been up to 2". It was cold, the windchill was getting to me and I was in a hurry, so maybe I'd do better with better ammo and more time. Attachment 43735
Also, I'm not good at pictures...

I use a lot of Russian steel cased ammo such as Barnaul/Wolf for training. Does anyone know if this barrel will cycle this ammo?
In Post #70 I believe Clint recommends dropping the buffer weight with Wolf. IIRC, he also didn't recommend Tula. Since I know I'll end up with PMC Bronze being shot through mine by others and possibly myself, I sent him the parts for my upper and he did whatever was needed for that to work when he assembled it.
