Have shot them with everything from a 22LR to a 458WinMag. They all died with correct shot placement. Lost one after I shot it with a 9mm, lost the blood trail in a rainstorm, poor shot placement on my part.
Why in the crap would you trail one?
LOL. I started to trail a big one once. All alone on the lease, right at dusk. Took about three steps into the mesquite thicket, then thought to myself "WTF are you doing?" The reason I started to trail him: to make sure he was dead. The reason I stopped myself: to make sure
I didn't get dead.
