Ok so i've got an Encore with a .270 barrel. Have not had to re set my scope one time since i put a Nikon on it about 4 years ago. Hasn't been bumped and when it's off it sits in the back of the safe. I did however take my regular encore stock off and put a pro hunter stock and forearm on it. Shot my gun today and about 6 inches high. It's perfect for right to left just high. Within 3 shots had it hitting right on again? Would me changing the stock out have something to do with it? It is a lot ligher now but never would have thought it would make a difference like that.
