Home Forums Hunting & Shooting AR and Tactical Rifles 6 arc or 6.5 Grendel AR for hogs

Of the 2 options you listed 6mm ARC.

But for a lot of other reasons, mainly cost of ammo & bullets for plinking or serious shooting in a variety of situations, I'd still stick with 223.

62 gr. Barnes TSX is pretty strong pig medicine, with lots of cheaper bullets for everything else.
