Planning a hog hunt up in WV, and I was curious if AR pistols are legal to hunt with up there? It will be a 300 blackout and on private land

Check the regs here: WV 2018-2019 But I don't think non-residents can hunt boar in WV.

Thanks, Ill take a look.

Its a private reserve and they have reviews from people from out of state, so Im assuming it would be ok?

If it is a private reserve, it may be registered under a "farm" type business. In that case, the hogs would be livestock. It's probably OK from that aspect.

I believe the .300 BLK pistol is legal for hogs, deer, and bear in WV.  We had this discussion in our hunting group when they reminded me I could not use my 5.56 AR pistol on deer because of this rule:

"It is illegal to:  hunt bear, deer, or wild boar with a revolver or pistol using a
straight-walled case of less than .357 magnum cartridge or a
bottle-necked case of less than .24 caliber."

You do need to buy a pistol hunting license.
