At what point would I need a 20 MOA base? I know, when I run out of elevation. If my intended self restriction is a maximum of 600 yards, would I need a 20 MOA?
Depends somewhat on the scope in question's total adjustment range. To 600, most likely not, unless you're shooting cannon balls.
Most times guys think that you'll automatically be in the middle of the scope's range when mounting with a zero base. Maybe, maybe not.....
Anything below zero is lost adjustment. No biggie if it's not a dialer, but no point in hamstringing yourself right outta the gate.
