What many don't think about or consider when bowhuntingthunder chickensis fly-off after a shot. It happens, and think about how difficult it would be to track a bow shot turkey after it flys off!! For that reason its best to lower your bows poundage, and use a large bladed mechanical type head to actually lower penetration, and keep the arrow in the bird. Some also use a carp fishing type rig with a string.
I prefer the NAP Gobbler Getters myself, becasue they are designed for less penetration. Thats why they have the blunt tip. I've never heard of a ricochet with this head, but suppose that is possible. But if thats the case chances are your shot is off to begin with! Every bow killed turkey I've taken has been with these heads, and I have yet to loose one using them. Another option is using a reg. deer hunting head, and putting a Adder Point on the end of your shaft. Cabelas offers them. This also has the same slowing effect.
I hope this helps.
