Alot of good advice and you left a few questions unanswered. Make sure your hunting with the same ammo you practice and sight in with. Most rifles sighted in 1" high @100 yards will be the same hold at 200. Practice, practice, practice. You can shoot a .22 just to get some trigger time and will help if your recoil shy and don't even realize it. Then practice some more. Don't shoot at the deer, pick a spot on the deer and shoot that spot.

In your darkest hour when the demons come, call on me brother and we'll fight them together.
