Friend of mine had a very bad day...
... a few years ago, in NC.
Went deer hunting with a 7mmMag. Rifle held 3 rds, so he had 3rds with him in the rifle, and that was it. Probably would have been enough, but...
... he saw a deer. He sighted in, took his shot, and the deer went down.
As he was approaching the deer, he saw another one. He took a shot, and missed; he then fired his last round, but missed again. Second deer vanished. (I guess NC doesn't have a one a day limit; never hunted there, myself, and don't know - but I wouldn't have shot at the second one anyway; too much to drag home)
Well, you may have guessed it, but at this point, deer #1 staggers up to its feet. My friend now has a wounded buck, and no more bullets. Buck tries to run away, but it's in bad shape, and not getting anywhere quickly.
My friend does not want to let a wounded animal get away (we discussed that problem in conjunction with taking shot #3 at a then-running deer, and he conceded that had been a poor decision, but he was happy he'd missed) and so he chases the deer through an Appalachian forest, finally running it down in a stream.
He ends up tackling the deer, and killing it with a Buck knife. Bad day for my friend, miserable day for the deer.
If he had it to do again, he'd have:
1) brought spare ammo;
2) not tried for the second deer; and
3) not taken a low percentage shot on a running target.
