Re: 338 lapua setup
A 20 MOA scope base is taller in the rear. Not level like a standard. Do you understand the concept? I was trying how to best describe it. Maybe someone else here is better at it. But because your scope is now mounted with an additional 20 MOA. So lets just say that you have s standard base and you site in at 200 yards and you want to shoot dead on at 600 yards because of the bullet drop you would have dial in 20 moa. Well after a certain distance your scope only has so much compensation for bullet drop.
So with the addition scope angle you stay in the scopes range of adjustment.
