Changing point of impact?
I can't seem to keep my Wtby 300 shooting to the same POI, it seems to shoot all over. I am shooting a stainless Mark V with a black stock topped with a 4-12x50 swaroski scope with 168 bergers and 83.5grs of H4831. I shot this gun last year and sent the scope back to swaroski to check the focus and they said the scope was fine so I remounted it nice and tight. it will shoot a .75 group at 100yds but everytime I shoot it it seems to move the POI, all within a few inches at 100yds but not in the same spot, any thoughts?
