Back when I was 'smithing I had a local state hunter who was hired to clear a local state park of a huge herd of feral pigs. He used a Ruger Super Blackhawk in .44 mag shooting SSK 325 grain bullets at 1400 fps... ouch. He asked me to de-horn the bottom of the hammer as it was tearing up his hand.
He carried a SBH as the pigs loved to get into the networks of manzanita and madrone and a person had to go in on hands and knees to get in there. He said his load shot all the way through the 300 pounders from any angle.
He lined up the local Catholic Worker Kitchen and delivered pick-up truck full loads of them till the park was cleared out.
