"Quarter" Minute of Angle

“Quarter” Minute of Angle


Here’s a simple exercise that you can conduct to assess the consistency of the overall performance of your AR-15, ammunition, scope and zero. You will need to down-load the 100-yard target (in .pdf format) that is pictured below, from the link at the end of this article.









As you can see in the pic above, the target consists of the images of ten U.S. quarters in a row, on an 8.5” x 11” piece of paper. The nominal diameter of a U.S. quarter is 0.955”; in other words, it is a sub-minute of angle target at a distance of 100 yards.

Post the target at a distance of 100 yards from your shooting point. Shooting from any position that you choose, with or without any support that you want, fire one shot and one shot only, at each of the ten “quarters” on the target. In order to score a “hit” on an individual quarter, the center of your bullet-impact must break the outline of the quarter.

The quarters should be shot at in consecutive order (left to right or right to left) in order to more easily keep track of any “collateral damage” (hitting one quarter when you were actually aiming at another.) Take as much time as you like in-between each shot, but at the end of the exercise you can only have ten bullet holes on the target.

As an example, the target pictured below was shot from the bench using one of my Krieger barreled AR-15s with match-grade hand-loads.







Is the performance of your AR-15, ammunition, scope and zero consistent enough to make a single shot on a sub-minute of angle target 100% of the time; ten out of ten attempts? 90% of the time; 9 out of 10 attempts? 50% of the time; 5 out of 10 attempts? Down-load the target and find out!
