Some shooting styles and philosophies are more difficult to complete when a live moving animal is involved. I had a friend that had a very long awkward form for his size. He, 5' 8" with a 68" arm span, spent most of his concentration on fully reaching his unnatural 29" draw when trying to shoot deer from a high tree stand. He shot high every time or failed to get off a shot. I gave him a shooting lesson that was done 100% while sitting on a ladder stand in my backyard, basing everything on the shot angle and the sitting position he was in and shooting down to my target 12 yards away. He lost three inches of draw, had his eye over the arrow, a solid anchor and follow through, he could melted his body into the shot and still maintain the proper arm and shoulder alignments. Most important, he was consistent. Boring a hole through it, picking spot, needs to be practiced on every shot, not just the shots we take at live game. It takes a little bit to keep the eyes fixed on the spot. Shooting with natural shot timing really helps when shooting at game, with a butt load of adrenalin and buck fever, the more automatic and natural the shot the better.
