Back a few years ago berrie talked me into using one of his new heads the called it the Rocky Mountain gator and it done the same thing to me. I shot a bull at 40 yards about three ribs in broad side and the arrow came out behide the last rib on the other side and went fying. It had a 2 inch cut kill the bull dead. but I didn't like it changing angle on me. It had floating blades and opened like the Rage.
