I'm going to need to have someone video tape me but I couldn't get this right today. Shooting a 20" 308 unbraked, resting the rifle on my collar bone, so my head is coming straight down. Shooting at a 100 yard target, and repeatable, everytime it looks like the rifle moves down and to the right, so my point of aim will move 6mil to the left, and about 1mil up, so not much down movement, but a lot of right movement of the butt stock. It doesn't feel like my rifle is bouncing off of me, but maybe my NPOA is off. I am trying my best to relax my shoulder/back and only use my bicep. After I shot it, I was very careful to move my entire body as I moved the rifle back on target, and that kind of helped, which makes me feel like it's a NPOA issue, but I am not sure how to check NPOA. When I unload the rifle, it stays on target, when I dry fire it stays on target. When it actual recoils, it does not stay on target.
I'll go out again and have my partner video me to see what the issue is...
