Good shooting weapon. According to my BC program, to be dead on POA at 150 (correct for the 100/150 setting), you should be just over 3 in above POA at 50, and 4 inches above POA at 100. You are probably sighted in at about 175 yards dead on. I wouldn't change a thing. You are close to that and WELL within mil-spec! For 100 yard match, you should be perfect as you are for a 6 o'clock hold on an SR100. Nice Weapon!
