Well ,did anyone ever think of the foot per second the bow shot at? I would never shoot a LIVE target with a bow at 50 plus yards. The prospect for the animal moving and making a bad hit is just to high.Take the best bow made and its Foot per second speed. Then figure the animal takes one step foreward. The step of a bull is at least 16 inches. Whack POSSIBLE bad hit.Bad choice. 1 shot ,one kill .If you cant do that stay home
