If they are the Texas wild hogs I’m thinking about you’ll need something pretty stout. They have a layer of gristle that covers their vitals, and I’ve found that nothing less than a .44MAG will penetrate sufficiently. I’d go for a nice lever action carbine in “at least” that caliber. A lever is light, and will give you quick follow-up shots while taming the recoil of the stouter rounds. While you’re at it get a good cookbook too. Wild hog is pretty good eating.
Thanks for the assist.
