Looking for some advise here. I've been shooting all summer long. My sights are dead on!! Last week I started shooting broadheads. From the ground they basically shoot the same, right on the mark. From an elevated platform (my roof) i'm shooting about 5"low.(my field points were also hitting low). I focus on bending at the waist, keeping my arm straight etc. and still hit low. The 5" is consistant, so do I adjust my sights or compensate high. I've been shooting 15' high and 20 yards out.
