We hunt hounds and curs both, they know what a shot means....it means a hog to them and they aren't bothered by it. I've been using an M1 carbine for over 10 years now.....yep, the old military gun from WW II. Short, light, even lighter if you'll put a synthetic stock on it. It shoots a 110 gr. bullet that won't go through a hog that's over 70 lbs. Not nearly as loud as a 30-30 or 35, but will kill a hog at over 100 yrds easy. Killed a bunch of hogs with it and only lost 2 that I knew I hit. Try one.....they're a bit pricey, you'll really like it. You can get a Universal brand for about $400 if you shop around.
I killed a lot of deer with an m1 30 carbine when I was a kid...
