I have a 260, shooting 140 gr berger, shoots pretty good .5 moa at 500. The problem I am having is the poa is drifting to the right. At 500 3 to 4 in, 750 is 5 to 7 in and 1000 it gets out to about 20 in to the right. Everything seems to be level, am even going to try to cant my scope tomorrow. Just wondering if anyone has had this problem.
