We’ve had hogs around here in east tn forever. My neighbor killed 4 off his lease in deer season using an Ar chambered in 223 with 4 shots. All were shot in the shoulder/lung area, 1-2 bullets exited. He said the smallest was around 140 and the biggest was 220. He kills quite a few every year, always with an Ar.
I’ve only ever shot one and it was with archery. It was a very large sow. I hit her dead center of the chest as she came out of some ivy and it exited her hind end, took the fight right out of her.
