The 10 twist is a bit fast for the lightweight .30 cal bullets. All barrels are different though, some like them, some don't. My .308 shoots the heavier 168, 175, and 178gr bullets much better than the 155's.

I haven't put many round down range with mine yet, but I am getting better than MOA at 100 yards. I have the 16" version

I didn't measure this group, but judging from the size of the boxes 1"x1"  the group looks to be about 0.5" This was at 100 yards with Atomic 168gr match ammo.



Edit: what optic are you using?

Shoot it with some regular ball 150 gr ammo for a while, im sure the nitride will smooth out and it will get slightly better
