Shot the moving target system for several hours (450+ rounds of .308 Win.) and we came to an interesting conclusion - 200 yard moving target was easier to hit (and our groups were smaller) than the 100 yard target. Speed was constant, target carrier had a backboard on it that was about 8' wide and 3+ feet high. Caught every round fired at ShootnSee circles or balloons so we could see where the misses hit. I put fresh paper on the backboard after each twenty shots, looked at the groups size at five and ten shots going each direction. Another wierd thing, our Right to Left moving groups were always smaller than the Left to Rights, even tho we usually find that Left to Right swing is easier to do. Got the barrel so hot on the rifle that we use for movers that my buddy raised a blister when he accidently touched it. This is a factory sporter barrel and it takes incredible abuse and just keeps shooting around 1 moa. Not long range but might be interesting to some guys.
