Shooter skill notwithstanding! After a shot, the bullet is perfectly centered left-to-right but exactly one inch below the target. In theory, your rifle would now be sighted to yards. You may purchase a product that says it has a 4 minute of angle dot. How does this translate into accuracy? Basically, you have the same principle. If you purchase a product that says it is 4 MOA, that means it will have a shot-placement dispersion of 4 inches at yards.

Imagine the shooter is at the center of a circle, and that the target is on the edge of that circle. The distance, or range, from the shooter to the target is also the radius [R] of the circle. If the range is yards, that distance is equal to 3, inches.
When we plug 3, in for R in our formula, the result is 2 x 3. Therefore, at yards, one MOA is equal to 1. The formula works for any range. If the range is yards, one MOA equals 5.
