I put a new site on my bow this weekend (jnh did) and while shooting found it was improving my groups at 40 yards much better than at 30. My 20 yard groups are starting to remind me of when I shot alot in the old days. My 30 yard groups just plain stink,,they may be on the proverbial pie plate but thats about it. The only difference in my pins is that the 30 yard pin is dark red and the other 2 are neon. On my old site I had moved my red pin to the 40 yard spot and rarely shot at 40. Does anyone else notice a difference in their ability to shoot different color pins or do I need to make an apointment with a shrink?????
