DIALING IN FOR YOUR BARREL LENGTH AND AMMUNITION
Using a bipod or sandbags, preferably on a bench or in the prone position, adjust your turrets to dial in your point of impact
to the center dot. Each click is 0.33 MOA, or 0.33 inch at 100 yards.
Your point of impact will vary depending on type of ammunition, barrel length, and altitude above sea level. For 5.56 NATO
and 5.45x39 loads, match your ammunition type and barrel length with your altitude above sea level, and zero your scope
at the distance indicated. For other loads, nd your bullet weight and velocity and zero your scope at the distance indicated.
Plus (+) and minus (–) numbers indicate desired bullet impact in inches above or below your point of aim. For example, a
shooter ring M855 using a 16” barrel will want to sight in a half inch high at 1,000 ft. above sea level, dead on to point of
aim at 2,000 ft. above sea level, and a half inch low at 3,000 ft. above sea level, zeroing at 100 yards.
