I think the three described points; start of the beard, wing socket, and where the tailfeathers come together, are your best bets for a good shot. It is my experience that the good "kill" zone on a turkey is just a little bigger than a man's fist from any angle at any given time. I have seen several side shots be a little too far forward on a bird and just rip the breast open,just for the bird to fly away and die. You will need to use a broadhead that will get very little penitration, for a complete pass thru runs too high of a risk of a bird getting away. If you just take out a wing, it may not fly, but it will run like hell. Good Luck and let us all know how it turns out!!
