RE: probly a stupid question but im new its about scopes?
If you sight a gun in at 16 power dead center at 100 yards and then knock it back to 4 power, it better be dead on. This was a major problem with alot of the cheaper scopes. Its cause of tolerances are too loose. Some say its best if the power ring is actually hard to turn. That means not much tolerance. I believe that to a point.
Second reasonI upgraded scopes.
