I was clearing some shooting lanes and marking yardage last weekend. Around my stand a 20 yd shot is going to be a long one. I am sighted in at 20 but feel my best opportunities may come at distances somewhat closer than that. At 10 yd I am about 3 in. high. Would there be any disadvantage to changing my top pin to 15 yd and avoiding the need to hold low for shorter shots?? What is your experience?
