I personally have built several 7.62x39 and 6.5 grendel rifles. I have two remaining, one uses an Aim nitrided bcg, the other is an Aim nickeled bcg with a Cason engineering bolt.
The Cason was one of my original x39 bolts and has had THOUSANDS of rounds through it first on a 7.62x39 Rifle then on my .264 lbc. It has been flawless, not even so much as a broken extractor. Its supposedly a super bolt and Im starting to buy into that. The Aim bcg is again a x39 and used on a .264 lbc , this rifle was way over gassed and I ran some pretty darn hot loads though it to boot. I broke one extractor at maybe 2000+ rounds. Aim sent out a new replacement extractor for free and was here in like 3 days. The nitrided finish is so slick, it is the easiest bcg I have ever cleaned, mostly just wipe it off, the fouling at the tail tend to just crumble off when any force is applied although some times I have to take a brush to it.
I have never broken a bolt of any caliber.
So what are yall using any issues or crazy high round counts?
