Hello! My son is 12 yrs old, he shoots a Diamond Razors Edge bow, draw length 27", draw weight 50 lbs, he shoots 2 to 3 times a week. My question is, when he shoots at targets he's not consistent, but when be shoots 3D he's dead on. We have worked through torquing the bow, he had Target panic for a bit got over that, now I'm not sure how to help with inconsistent Target shooting. When he shoots 10 yards, he's good, 20 yards is where he falls apart. Any ideas?
