Some where I have the tables that are the starting point, decide what grain bullet you want to shoot and I will get you started, I spent a long time with the nice fellow that did R&D on the BOSS system,36,000 rounds in a 100 yard tunnel with a 36X scope. Winchesters were shooting 1/4 inch many times with factory ammo. very best winpoor
