RE: 3/4 inch groups ?
Practice as much as you can. Concentrate on every shot and make sure you hold the follow threw. Alot of times when i miss its because of that which causes a slight jerk so i miss the mark by a couple inches. That was my big problem and still is come every june when i break the ol bow out. Practice and concentrate on the shot. One thing which helps me is shooting at very little targets. I like to shoot at golf tees stuck in my target. I concentrate more on the lil things. Aim small miss small. Always pick a spot on a deer to concentrate on and make it small and you wont have any worries.
