I can't believe nobody posted the obvious solution. Try it on the range first!

Rather than discuss if a running shot is/isn't ethical or possible, try it with your equipment on a moving deer target at various speeds and distances.

If you can get consistent hits, you can consider the shot out in the woods. Otherwise, forget it! (This goes for long distance shooting, snap shooting, etc.)

HSA has a simple, inexpensive moving target carrier design We're prototyping several more.
