what always bothered me were stories of...
"well I was on a combo hunt... for say blacktail and grizzly..."
and I saw a big grizzly when I was deer hunting and had deer ammo in my gun...
I'm mostly a 1 gun, 1 bullet guy, if it'll kill and elk, it'll kill a deer,, but the reverse is not always ideal IMO.
also some of these shows, no one reloads quickly, i've seen game get hit, drop, get up, run off, had the hunter been ready...reloaded, they could have got off a 2nd shot.
