Rifle Scopes 0 or20 moa mount

This will vary because of the ballistics of the bullet and velocity but my Remington 700 LTR with a 20" barrel and 2540 velocity and Sierra 175 gr Matchking needs 43 MOA Elevation to reach 1000 yards. If you don't have that much elevation available in your scope, get the 20 MOA mount. I use a standard mount but only shoot to 700 yards.
