Thats very hard to believe doedumper. I have used it many many times in every brand of bullet and have had no problems whatsoever. Dont take offense but it sounds like you just plain gut shot her. The tiny rib on a deer just aint gonna deflect a bullet to take a 90 degrre turn, sorry i aint buying that. It might deflect it say 10 degrees but it aint gonna do a u turn.
