My experience with bows is all "ancient history" now but I know a lot of guys who are passionate about the sport.
A friend of mine recently brought an expandable head that he's been shooting to show me. It's the Rage with 2 blades. It is one scary looking broadhead.
He uses carbon shafts and uses "The Block" as a practice target. He tells me that about 1/2 of the arrow penetrates "The Block" with his bow set at 50 lbs.
He's shooting a new PSE X-Force bow with a speed of 300+ fps, chronographed and only needs 1 pin out to 40 yards.
I'm sure that would pass through a turkey but it would cause enough trauma to put him out pretty quickly.
