Big Butts are usually shot before hauling them in too. But it's still a wrestling match to get them in and
they can "come back to life" if the brain was missed. I was just sayin' I don't like the idea of a semi auto gun for this type of thing. Too much going on, a short muzzle that is harder to keep pointed away from others (or the boat) and a loaded chamber all during the excitement of taking a large animal than can seriously injure you.
The guy I've been going with uses a 38 special bangstick. When I get my own Butt boat I'll prolly get one of these http://www.galleryofguns.com/genie/d...item=sb1%2D41n
It can dispatch big fish and be a stuck on some remote beach survival tool.
