Thank you Chris, I checked the rear screw and it was a little loose but not too bad. We have a storm coming Thursday and Friday so I won't get a chance to shoot till Saturday. Did you have a settling in period with your gun or did it just shoot good right from the begining? For the most part my groups were good from left to right but were not that great up and down. I was making alot of scope adjustments from one brand of amo to the next, do you think it is posible the scope didn't have a chance to settle in? I would say 90% of my adjustments were up and down. The scope I'm using is the one that came with it, I think its a 4 power Winchester scope.
