I think I understand MOA as it relates to point of impact on the target, but maybe I'm missunderstanding that as well. What is "20MOA" and "30MOA" and how does it relate to mounting my scope on my grendel? I'm running out of time b/c I need this completed to hunt rifle season in MI.
the mount has a built in extra amount of elevation (20 or 30 moa) to it. Basically, the mount is cut at an angle. Normally, you'd mount a scope and zero it at 100 yards. In a perfect world, your "zeroed" scope would have it's elevation turret right in the middel of it's adjustment range........giving you the same amount of ability to adjust your aim upward or downward. Since you really need a whole lot of ability to adjust your aim point lower (for bullet rise), the angled scope mount allows you to use more of the turret's adjustment range to compensate for bullet drop at long dstances than if you had a flat mount.
For example, if you have a scope with an 80 moa adjustment range (+/- 40 from the middle). with a 20 moa angled mount, you now would have an adjust ment of -20 moa to +60 moa.....allowing you to adjust the scope for bullet drop at a distance that you normally couldn't adjust to (without holding over the target) with a flat mount.
Sorry for the verbose answer, but I think I explained right.
