started shooting my bt65 and my 69$ Walmart center point ao 4x16 is not going to cut it.Don't get me wrong for the money it's a great scope, when i got it dialed in and worked super on the Benjamin np2 trail. But shooting from 50 then out past 100 yards this scope is not going to work for me.I am looking for a scope that the up and down settings work fast.And suggestions?
