20moa mount on a 20moa rail.

At this time I am not looking to do elr. It's a 6.5 Creed 26" AI. I ask only cause I have an extra mount lying around. The scope currently is a Bushnell XRS 4.5-30
Having 40 MOA shouldnt be an issue with that scope and ammo combo. I have a bushnell ERS 3.5-21 on a 6.5 and i have 28 MILS of travel after zero with just the factory 20 MOA rail and rings. U basically get about 6 mils more of travel per 20 MOA, but like i said just be careful cause you dont want the zero all the way at the bottom of travel, you want it some where right around a third of your total travel.
