I hear ya 340.....I rarely have a deer run more than 5 to 10 or so yards, with about any bullet, exit or not, when hit on the shoulder or tight behind it. A far back lung or liver hit and they'll often run a 100-200 yards, if that far, then bed down.

I am always amazed when people tell me a solidly hit deer runs 100 or more yards. Elk running downhill maybe, but not deer. That's just not been my experience.

Heavy for caliber bullets do seem to hit harder, but lighter bullets up close when they still have their speed have treated me well.
