Ive killed them with .17hmr and .22lr before as well with shotguns , .44mag and .45acp, but my .223 does its job in the groves
Closest encounter Ive had with a piggy was in a palmetto patch taller than me and charged by a 300lb+ boar...He cut my pants from my knee to my crotch but he did'nt make contact with skin, Thank god...
