When I was a kid, not knowing any better, I shot a buck at 50 yds in the ribs with a .222 loaded with the Sierra 55 gr Semi-pt.
The buck ran off and we could not find it.
Who the [bleep] would shoot a deer in the ribs? That's a liver or gut shot at best. If you had shot that deer where you should have (hint: between 1/3 and just under 1/2 way up it's front leg) you would have a very dead deer.
