I was at the range this afternoon shooting a Steyr .308 rifle at 100 yards. Eventually I ran out of target spots I placed on the board so, with a few rounds of Hornady Match left, I went after someone else's left-over black dots.
The first picture shows I managed a decent 5-shot group just about 1/4" into, and below, where the black dot was. With a target change pending and only 3 rounds left, I moved to another black dot about 12" above this one.
Not a terrible 3-shot group but, how on earth is it an inch or so lower on the target board than the previous group?
The only thing I, and a few range pals, could figure is the target boards lean backwards maybe 15 degrees or so. That still doesn't make sense to me, I'm aiming at the dot. Maybe the barrel reached a heat point after the first 5 where it just started dropping the rounds a bit lower? BTW, it was on and off raining all day, maybe the rain drops forced the last rounds lower
Anyone else notice a change on POI just from aiming at different point on the target board?
