Electronic scoring.

When you say "full size silhouette" to which version are you referring? High power, smallbore, lever-action (which of the three?), black powder, etc?

There are a few rules that would have to be contended with when considering this option... such as "the target must fall off the stand to count". Can you "ring" an electronic target like a 6mmBR can ring a high-power ram? How many great memories are created by an animal that just barely hangs on by a toe or turns a full 180 on the pad?

I'll admit that one of the most charming aspects to silhouette is to hear the "ping" and see the animal fly off the rail when you get a good hit. You just don't get the same visceral feedback from paper or electronic targets. There are concerns in the Olympic/3-P crowd that the Olympic shooting events will eventually end up with just electronic targets and laser guns with none of the minutia involved in getting a great score with projectile-launching firearms.

Having electronic targets for practice (an excellent resource) or for tough situations where the traditional range setup can't be attained... Sure. A replacement for the game we have now? I'd rather not.
