This is with either 30-06 150gr flat bullets or my .50 cal flintlock 320gr maxiballs:

When my shot hits high near the spine, the deer goes down in it's spot. A solid hit to the heart makes a mess all around the deer and it will try to drag itself maybe 5 yards. When it goes through just the lungs I have to walk maybe 40 yards after it. Only once did a buck start walking again as I pulled the trigger and the bullet connected under the mid section driving a piece of bone through just the skin ripping a 10 inch tear under the belly and that deer went almost 200 yards barely dripping blood with it's innards hanging out. As I tracked it, the buck jumped out and I gave it a finishing shot.
