MCRANCH does not really mean "cant", he means "slope" for a Picatinny base or a one-piece scope mount. For example on my Ruger Precision Rifle I use for long range competition I have BOTH a 20 MOA slope n my Picatinny rail and the Nightforce Unimount. That's a total of 40 MOA for extreme long range shooting so I do not have to use up all my vertical turret adjustment.
Cant is the amount of lean, left or right, you make to the rifle when shooting. This lean throws your bullet left if you lean right and vice-versa.

I don't think he's asking for how anti-cant indicator works. He's asking why would he need a 20 MOA base when a Vortex Razor has a total elevation adjustment of 125 MOA.
I was looking on line at the Vottex Razor, it said 125 elevation and 125 windage. If it takes 45 moa to achieve 800 yards then would this scope require a 20 cant to achieve that yardage? Confused thanks for any input.Also new to this sight.
Cant is also used in describing the angular relationship of how the scope is mounted in relation to the barrel ...
On either case, it's best not to hijack this thread.A 20MOA base is canted down in the front toward the barrel. By canting the base down in the front, this is what allows for more usable elevation adjustment in the scope. (20MOA Explained - Warne Scope Mounts)
My sincere apologies to Lievois if I strayed you off course.
