I had shot against people trained in HP that had production ML's and were always fiddling with their sights. While I do agree that they were not that high of quality of sights, it seemed like those of us that had fixed sights did better through the whole season because we left our sights alone while they were always chasing the zero. One issue was that different clubs would get kind of creative on their targets. One liked to use animal targets for instance. Also in the "primitive" fun shoots a 6 O'clock hold is absolutely worthless, where you migh have to break a charcoal briquet or whatever. In one team shoot, the first shooter would shoot into a circle and the second shooter would try to hit the same hole, closest won. For these a 50 yard sight in was plenty. They were also fun to compete in as some of the prizes were quite attractive.
