Welcome to the forum. If you are wanting to decapitate turkey, the Magnus Bullhead or Gobble Guillotine is the way to go. If you are just wanting head shots, any broadhead will do the job. Even a field point should kill on a head shot. (Probably illegal though) I'm like LB, and use the Rocket Hammerhead expandables for body shots. I have seldom seen a turkey keep it's head still long enough for me to have much faith in a head shot. I know alot of guys do it on tv, and it looks fun, but I have to wonder how many misses they have before they connect.
