Your best bet for stopping turkeys is to use a setup so you don't get a complete pass through. A arrow stuck in the bird prevents the bird from running off, or worse yet flying away. Its recommended to crank your poundage down, and use a tip that'll slow penetration. I use my bow for both deer & turkeys, as the seasons run together in the fall here in NY. I leave my bow at 60lbs, I use NAP Gobblergetter broadheads. I arrowed 2 turks this fall with the setup, and neither went out of sight from the hit.
