When I went to zero my SN-3, I had to dial on a ton of windage adjustment, just to get to zero. So much so that I have no more numbers on the stem under the turret. Did I do something wrong here? It shoots well enough, almost 3/4 moa w/me driving(kinda new still), but i'm worried something wrong. Please, advise what I might need to look for.... Thanks, Duke.
