Just this past week a rancher friend of mine in Northern California killed four smaller pigs with one head-shot each with the 17 HMR that he carries on his quad. I don't know what ammo he was using. He carries the HMR for ground squirrels, and shoots many.
These were the first pigs he has shot, as pigs have just started to be a problem on his ranch. I saw what they were doing to his irrigated pasture. What a mess they were making.
