Shooting bales, or even 3-D targets in the back yard or by yourself at the range is different. 3-D isn't hunting, but it's as close as you'll come. You have pressure, you have unknown yardages, uphill, downhill, through the bushes, etc. Lots of shots you probably wouldn't attempt on a live animal, but they still help over-all. Besides that, it's a lot of fun.
I agree with ya LBR, things are a lot different outside the "comfort zone".
