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!
This makes me want to try taping some pennies to a target, and then fail at doing this to them. I wonder whether it would put a hole in the penny, a hole in the cardboard, or both…
This is great. Dad and I played poker, horse (like basketball but with AR’s) and other games at 25, 50, 75, and 100 yards with my AR and the one I built him. This quarter target would just add to the fun. I’m thinking of adding all denominations of change and whoever has the most money after X shots at X yardage wins.
this is a range gun. I am shooting for groups. I don’t want to destroy my aiming point with a ragged bullet hole.
Recently I glued the barrel extension into the receiver with locktite. This changed the barrel harmonics so much all my old loads were no longer accurate. I am having to rerun all my load development. The picture below shows a series of groups shot today with 69gr. MK and CFE223. Each group is 0.2 grs higher. As you can see one load stands out. If I were aiming at a group of bullet holes instead of the little red x my group would be larger.
Now I will load up 25 of this load and some others I have found over the last two weeks and shoot the MOA challenge. See if this is a fluke or real.
takes me one or two shots to zero to the bulls eye if I want.
Finally got out today to break in the barrel with some cheap AE XM193 and made two attempts on the quarter targets before the rain hit.
Never shot here before, should have brought a stool.
Benches too short for me and bolted down stools made it real short.
Now my excuses are out of the way :rolleyes:
