Record qualification on the final day of BRM in the Army. As a young E-1 shooting an M16A1, I was shooting very well, knocking everything that popped up except one of the 300m targets. By the time I was able to spot it and get on the irons, it went down - so much for a perfect score. I knocked down the rest of my supported shots then when switching to unsupported I kept an eye out for that hard to see 300m target. When it popped up again I frantically got on the irons, walked the front sight post up to the shoulders and started squeezing. It seemed like an eternity for the shot to break and the longer I squeezed, the more strained I got and the muzzle started to wobble. When the shot did finally break I saw that it was quite a bit off to the right of the target. However, I also saw a dust puff off the edge of a pine tree stump about 50m in front and to the right of the target. So I obviously jerked the shot to the right and hit the tree, but the guys behind me were saying I hit the target. I told them it just went down at the time it was supposed to, but they were all saying "no man, it went down before the targets in the other lane - you hit it!" And sure enough, when they called off scores at the end, I indeed shot 38 out of 40. So how did I hit that 300m when I know the shot broke to the right and I saw an impact on a nearby tree stump? The only reasonable conclusion I've been able come to all these years is that I made an unexpectedly lucky shot on the tree stump that chipped off a high velocity piece of bark that struck the plastic target, triggering a hit.
