Haven't got to take it out yet but bought a marlin 44 mag for a hog gun.
For the Rambo's out there!
already suggested it but i guess everybody here is too chicken!
Who appointed you? Look, you want to take your little .223 out and shoot hogs, go ahead. I would rather use a larger caliber and have more leeway than you have with your 5.56mm..LOL. And who appointed you almighty ruler of what is ethical and what isn't? Don't answer unless you are high enough up in wildlife management to make a legal change; otherwise we don't care: you're just running your mouth on your opinion.
Besides, you're wrong anyways. .50 BMG is the minimum. Anything less than pink mist on impact is unethical. If you don't want the hog to run away and die a painful death do it your way. If you want to at least to be an ethical, responsible hunter, do it my way. Up to you.

None of them, you need more cartridge to reliably take hogs, .243 Winchester should be minimum.
