Yeap that's correct. Most guys are running a 4002. You may be able to use a lower mount if your bell housing can clear your barrel. 20 moa usually will get you out to 1500 for most calibers. I run 30 moa to get to a mile with a 6.5 creed.
Joking aside to be clear the wedge cannot clear the side turrets, however you don't need the wedge to true your scope. You could cut the wedge to clear the turret if you really wanted to use it to level the scope.
