A recurve shooter in SE MN, has killed turkeys with them with a nickel glued on the front. Our area biologist swears by them for turkeys. When I stated that it would take a head or neck hit with a 9/16" blunt,(which is legal in Iowa). He said to hit them square in the wing and a decent bow will do the job. A few years back a hunter where was hunting turkeys killed a turkey with a screw on bludgeon, I imagine a nickel fortified HTM could do about the same. I use Herters four blades for turkeys myself.
