Hi guys, just wondering if any one could help me. i have a springer that i have had from new, its been well looked after not been dropped or anything, but it hasnt had a lot of use. the other day i fitted a scope to it, its a quite old 3-9*40, i know the scopes fine as it worked ok on my primary gun for the last 3 years. So heres the problem, i zeroed the gun to 20 yards and was hitting about a 15mm group, but [bANNED TEXT] i shot at a target at 10yards away i hit the same group but about 60mm to the left of the target. I have never encountered this problem before does any know why this is
