Hmmmmm.... I was looking at broadheads and mechanicals today at Len's place. They make a mechanical(don't remember the name or anything) that has a 3 blade 3 and half inch cutting diameter. Now that baby would field dress a woodchuck. Can you imagine a cut that big. I wouldn't ever think of using such a thing on a deer, but maybe on a chuck.<img src=icon_smile_big.gif border=0 align=middle> Of course, the head was so long to accomadate the blades it would probably bend and be totally out of balance after one shot. No way would the blades last more than one shot. They'd probably snap in alfalfa.
