One thing to consider is are we talking Russian hog or feral hog?
There's a difference.
Some of the better advice I've read here is getting a Mosin.
Shoot they are cheap enough.
Lots of them can be found in the sub $100 range.
Heck I just bought a m44 carbine last week for $50. Really!
They basically have the same iron sights as a M1 carbine.
Improved ballistics. I believe they're more accurate personally, at least at longer ranges.
Plus presto you just increased your gun collection.
What wrong with that?
Nothing.
Surplus ammo makes them cheap to shoot. And there a variety of it now.
