I shot a 150 lb whitetail buck running toward me at 65 yds. The 130 gr X from my 7mm STW hit the buck between the eyes(not intentional) and exited behind the left ear, entered again in front of the left shoulder, traveled the entire length of the deer thru the body cavity and exited next to the anus. As far as I know, it's still going... Needless to say, it was a picture perfect bang-flop.
