I know its last minute but a buddy decided he could go deer hunting next week if he could borrow a rifle so I offered him my 30-30, it previously had a scope on it but that all got sacrificed when my girlfriend got a marlin 44rem mag last year. So I went and bought a new weaver base and borrowed a Leupold 2-7 and a set of rifleman (LOW) rings. I tried to bore sight it but it was way low, ran out of elevation it was so low, thought maybe I was doing something wrong with the bore sighter since I had just got it. Took the rifle out and shot it at 25 yards and it shot at least a foot low. Took the scope off and tried the iron sights for him but they are 9" to the right at 50 yards. I can try to move the front sight, but I would much rather have a scope for him. Do you think putting a set of high rings on would help out do I need to shim the base?
