Your load seems awful slow, im running the 34 v- nitemares at 3850fps in a 24" barrel
I was able to get 3750-3850fps with pressure, but accuracy isn't there. This is a 20" AR build, so I won't expect the speed from a 24" bolt gun. Plus, the powder I was using for those speeds is running low and prefer to use it on a rifle I use more. Did some rework with some 40gr Bergers this weekend and was able to get .75 moa with multiple charges of H335 at 3500fps. I'll just stick with those for now and work up until I see pressure and see where accuracy is. If it doesn't get more accurate at higher velocities, I'll be happy with .75@3490 FPS, especially for what I'll be using it for.
