thank you guys for the answers. The thing that seems bizarre to me is as of Vortex instructions I am to turn elevation turret all the way down until it stops, then take turret cap off and zero rifle with internal adjustments. When zero'ed at 100 yards set zero stop and put turret cap back on at 0 on the scale. I just wanted to make sure that this process wouldn't change with the 20 MOA base.
