Yes it happened, I have used X bullets in the past with success,all complete pass through's. This past week this deer was taken with with a head on slightly quartering shot through the chest.The distance was 120 yards using a 300 wsm pushing a 168 gr Barnes TSX to appx 3100 fps. The bullet destroyed the vitals and did get some intestines. The bullet was found on the off side just under the skin and to much surprise it just showed some rifling marks. This bullet penciled through and showed no signs of expanding, as a matter of fact I could load it again if I wanted to. This does concern me as it is possible to have a X bullet pencil and pass through a game animal and never know. This deer ran appx 70 yards and never bled a drop but fell in a open area so was easy to recover. Anyway you look at it, the bullet killed this deer and did's it's job but not as advertised. I have heard stories/internet woesof this happening but this is my first "hands on" experience and now know they are not the perfect bullet....of course there aint nothing in this world that is except my Savoir.

Through the trusty services of United Airlines, my luggage and deer are somewhere abroad and when I get I will post a picture of the bullet.
