Clothesline strung between bicycle wheels giving about 25 yards travel for a life-sized deer target mounted on plywood. The idea was to get your rifle on a pie plate, stapled to the deer's chest.
I've seen a simmilar set-up. Secure a plywood circle to the outside of an old truck tire and tape on a paper plate. Then roll the tire down a hill (from behind and to one side of the shooter). The tire will move as fast as a deer and will bound over stumps and rocks just like the real thing. Try hitting that plate on a bet!
Oddly enough, I have pulled that shot off in the woods. I'm not proud of the desision or the style of hunting used in those days, but I'm glad It turned out well.
There was a refrence to walking shots with archery a while back. In my opinion this is a BAD idea. In fact, I think it is worse than a running shot with firearms (at least in terms of wounding). A poorly placed gunshot wound will often cause enough trauma to knock a deer down and allow a follow-up. A poorly placed arrow amounts to coyote food.
Again, it's standing shots only for me these days. It is much more in keeping with the ethics I was introduced to as a small child. It is much more about what you take in with your senses than what you hang from the meat pole. It's kind of hard to have a real natural experience when you and ten of your buddies are driving deer and slinging lead.
