That sounds like a good drill Rick, its hard to practice for hunting situations isnt it? No matter what you do , it never quite simulates a real hunting situation. I do think that what you are doing will benefit any hunter though. Making your response more reflexive, and not having to think about the basics of shooting will make anyone a better game shot. When my boys were just starting to deer hunt, I made a running deer target by stretching a tight wire between trees, and suspending a cardboard deer target on it with a fishing line attached and run through a screw-eye so I could stand behind the shooter and still reel the target across. We had some fun with that, and it did sort of simulate live targets. I would stop it behind trees, and move it at different speeds without telling them what I was about to do. After awhile it got to the point where I couldnt make them miss or produce a bad shot, so we moved on to something else. Im sure there are some that will brand us "unethical" and stupid for even thinking of shooting at a moving deer, but I do think that overfamiliarization with our guns may be the best practice short of actually shooting game. You can only do that a few times a year though and its not realisitic to call that practice, its more like experience. It all adds up, and the more we shoot the better we get, right?
