I've hunted with everything from a 20 gauge to .243 to a 30.06 and rarely have I dropped one in its tracks. A handful that I can think of. I always try to shoot the crease behind the front shoulder but have taken one or tow chest shots and some shoulder shots. In saying that 95 percent of my deer travel some distance after shot. Most often less than 50 yards with a rifle. One or two that were shot kinda back went further but that's it.
