I have a m77 in 25-06. It is the model with the two stage safety not on the tang and has the medium barrel. This is my whitetail hunting rig and I was getting .75 moa out of it. I took the stock off it last week to clean it (first time I ever did) and now the damn thing is shooting all over the place. Can anybody explain to me what the hell went wrong? I called myself putting in back together the same way it came apart.
