Maybe a dumb questions. Nevertheless, got benchrest setup etc.. No need to go into specifics. First 2-4 rounds 1/2 to 1/4 MOA then the darn flyer ALWAYS NOT THE FIRST OR THE SECOND, ALWAYS THE THIRD OR FOURTH ROUND. The fifth back in group-it is driving me ##########. I have tried everthing-including completely hands off-free recoil to everything else. Again always not the first or second round (doing 5 shot groups)-always the third of fourth round. I know its shooter error-but what am I doing-what do you suggest???
