LOL! Nice try. I was waiting for a post like this. In fact, straight up, you beat me to it.
I'll play along though...
Why not just use a .117 caliber pellet gun? They have some now that are over 1,000fps. I think if you let fly a well placed shot right at the heart at a close distance, like from a well blended ground blind, you can down 'em in less than 75 yards.
