It really boils down to the specifications of the specific scope on the amount of elevation travel. Many scopes have about 70 MOA of adjustment range which means if the reticle is centered you have about 35 MOA of elevation adjustments left. As an example with one Leupold 3-9 scope I had about 70 MOA of adjustment. I ran out of elevation at around 800 yards at 450 feet above sea level with factory Hornady A-Max at 2425 FPS. Going to a 20 MOA mount allows we enough elevation to shoot past 1000 yards with this scope.
The elevation where you shoot has a bearing on whether you need a canted mount because of the thinner atmosphere at higher elevation. If you shoot at 8000 ASL you might not need a canted mount depending on barrel length/velocity and bullet BC. At sea level youll usually need a canted mount with a 6.5 Grendel to get enough elevation. I use 20 MOA mounts on my AR-15s in 6.5 Grendel and a DIP 25 MOA mount on my Cz 527 24 barrel 6.5 Grendel.
There are scopes that have 50 MOA of elevation so Im sure Id use a 20 MOA mount with that scope. I have a couple of Warne one piece 20 MOA mounts that are gtg and are not to expensive.
