Ok, I know how to BZO an A1 & A2. Even have a stack of the right targets to do the job. Anyways, I now have a Stag M4 with a 1/9 bbl. I have to sight in the BUIS, Carry Handle, and Aimpoint. My question is, since I plan to shoot various makes & weights through it, what is the middle ground weight to BZO out of the shorter barrel with this twist. Figure that I shoot on the low side at 40gr. and the high side of 69gr. What is the best weight to do the initial 300m BZO. Normally, I BZO all my weapons with Mil-Spec ball and weight, 230 in .45, 115 in 9mm, and 55 in 5.56 in my original SP-1. This is my normal plinkin ammo too. And Im pretty much leaning towards the same here. But I figured Id ask here first, see if anyone had any different thoughts. |
