I am haveing a little problem. Last week I was shooting my bow and everything was great. So went out bowhunting and thank god I didn't shoot at anything. I went to shoot tonight and my first shot was a ten inches high thought maybe I jerked or something shot two rounds and was high. so I adjusted my pins and was back in action or so I thought... It was getting to dark to shoot 30 and 40 yards so went back to ten, and was dead in the bullseye, but should have been a bit high(used my twenty yard pin for both) so I went out to twenty and was 3-4 inches low and the same with thirty. I don't use a kisser button but douse a peep. Do you think that I need a kisser or could the peep be sliding or if ancor point moving? Any Ideas would be helpfull. thank you.
