RE: how to relax win he comes
1) Get into some type of simple routine for every shot. Like a 3 step routine---anchor-form check-sight in-release.
2) Get a 3d target and incorporate some realistic shots into your target practice routine. Imagine you are in the woods. Imagine the feeling of the hunt. Imagine the sight of the deer moving towards you. Then get into your routine and take the shot at the 3d target. The better your imagination, the better the practice.
3) Hunt and shoot more at live animals. Squirrels, rabbits, wood chucks, or whatever you have in your area. Remember your routine as you take the shots.
Good luck.
