I remember one time I watched my wife shoot a pronghorn buck at about 120 yards, perfectly broadside. I watched the bullet impact about 1 inch behind the shoulder and 1/3rd of the way up the body. Pronghorn took off and I could see the blood behind the shoulder....and it kept going, and going, and going...and then I noticed blood running down the opposite side rear leg...wtf?
What happened was the bullet hit a rib on the on-side...turned not quite 90 degrees, ran down the side of the body and exited the off-side hind leg. Probably will never see that again, ever. I'm sure if that was on video, someone could make the claim it was the hunters fault somehow. Luckily we were able to watch the buck bed and got another bullet in it.
