Perfect Practice to Shoot
I have read many articles on how to site in your gun, and this isn't advice on how to do that. But being at the range isn't realistic to hunting Elk, so after you have good groupings at the range, get out in the field, set up targets at different ranges, and here is the key, do 10 sprints at 100 yards, make your knees weak and get your heart pumping strong. Then take a couple of shots at each target, from different positions. This will bring you as close to realistic as it gets.
I never have been around anyone hunting that has felt completely calm like you get at the range. Most of the time we will be nervous as heck, with our hearts beating out of control because you are so excited. This is a great get-n-shape advice as well. Do this twice to three times a week and you will be ready!
