I've got a 17 HMR that would routinely shoot 1.5 groups last fall with 20gr CCI FMJ. Never did go calling, shot a couple rabbits with it then it sat in the safe all summer. It was zero'd at 100.
Shot it last night and it was shooting an inch and a half left, groups were about 2.5 to 3 inches with 20gr CCI FMJ! Was wondering if the cold weather had something to do with it so I went and bought some 20gr Hornady XTPs.
Shot again tonight, high about 6 inches and right about 3 with both Hornady and CCI ammo. No wind, about the same temps as last night.
I don't understand what is going on? The scope on it is a Cabelas Pine Ridge, i'm starting to suspect its not holding zero?
Any thoughts appreciated, thanks in advance!
