last year my son shot a large bodied 9 pointer from 9 feet up and 20 yards or so out with a 47 pound Hill style Big River on Howard Hill's birthday. Blew a rib going in and rib going out with the single bevel No Mercy on a Sherwood. He could not believe how far his arrow was stuck in the ground. After he dressed and tagged the buck, he dug a hole to get his arrow back. Buried up to the ferrule in a tree root, but the ornery bugger got his complete arrow back with no damage to the arrow, but the tree suffered a bit. On the other hand I have field dressed good number of deer killed with standard Eskimos from 36 and 38 @ 26" bows, they don't have penetration issue on whitetails either.
