I shot a 5x5 bull with a 125 rocket steelhead..It dropped him in his tracks..my arrow deflecting and shattering one of his vertabre might af had something to do with that but it still looked cool.It was my first bowkill.The same year I had clean pass through on whitetail..He made it 40 yards..The next year I hit a nice 6x6 right in the shoulder blade...My arrow stuck in about 4 inches..I watched him go down the hill stop grab the arrow and pull it out...I've switched back to fixed blade..
