I will PM you as to not clutter up this thread.CTairgunner, that totally makes sense about 1 reg, me and a buddy both got m3 25 cals at the same time, he has done every power mod you can do and cannot get it to shoot right, he has the tungsten hammer huma port & probe, power block & 800mm barrel kit, front reg at 170 rear at 150, velocity with nsa slugs are just all over the place from 920 to 1035, groups are terrible, hes tried everything, any suggestions?
