I practice at given ranges at spot targets. I do lots of this throughout the year and at ranges far greater than what I would ever try to shoot a deer. I feel this gets my consistency down and my strength up. I also shoot at deer pictures or 3D targets. This simple helps me pick a spot behind the shoulder. I believe this is the most important part of hunting practice-the years I have done lots of practice shooting at deer shapes my shot placement has been much better than if I just shoot at circles.
