A 2.26 unity mount puts the sight 3.475 over the bore.
A 25 yard zero with 55 gr ammo going at about 3100 fps will put you on at 25 yards, 3.2 inches high at 50, 9 inches high at 100, 16.9 inches high at 200, and 18.7 inches high at 300.
A total garbage zero. It’s the most common I see people use at indoor ranges with these mounts. These people have no clue where they’ll be hitting at distance. They’ll totally miss the target once they leave their indoor range.
With a 36 yard zero, you’ll be 1 inch low at 25 yards, 1.2 inches high at 50, 4.9 inches high at 100, 8.8 inches high at 200, and 6.6 inches high at 300.
Not very good as you can see. While it’s not as bad as the 25 yard zero, it’s still almost unusable.
With a 50 yard zero you’ll be 1.6 inches low at 25 yards, on at 50, 2.5 inches high at 100, 3.9 inches high at 200, and 0.7 inches low at 300.
As you can see, 50 is much better. You’ll still be up to 4 inches high at some distances which you’ll have to compensate for that you wouldn’t have to compensate for with a normal height mount.
A 75 yard zero puts you 2.1 inches low at 25, 0.9 inches low at 50, 0.6 inches high at 100, 0.2 inches high at 200, and 6.2 inches low at 300.
This is the flattest zero from 0 to 200. It’s the most usuable. At 300 all you would have to do is aim one dot high. Even if you forget to, you’ll still hit low on a chest. This is the zero you want. If you can’t get good groups at 75 yards with your dot, use a 50 yard zero instead.
