I have seen this discussed before but could not search out any threads. I am wondering if there is a definitive answer as to if pitch effects POI. I have been told yes and no from some experienced shooters at my club. The issue for me is I seem to shoot better with less pitch (0 with 1/8 inch pitch spacer) or even negative pitch with 1/4 inch pitch spacer, and I am trying to figure out the effect and how come it effects my shooting.
