Another question by the turkey hunter
OK, I mess with a 11yd shooting space
in my house with a bb gun and a pellet rifle .177
sort of an idle time distraction.
if the scope is dead on at 11 yards (33feet) would it have to be
re-calibrated if I changed up to 50yards shooting for the pellet rifle?
I know the drop would have to be adjusted but what about left and right?
Just curios. My first guess would be no.          

Try this calculator, you should be able to find out
