I carry a Ruger Super Blackhawk single action revolver with a 10 1/2 inch barrel in .44 mag on my tractor. I've found that the hogs will pretty much ignore me when I'm on the tractor, or they are already running away when I see them. When they ignore me, I shoot them. Best encounter was when about 30 of them walked into the field I was mowing and I drove right between the group. A third went by on one side, two thirds on the other side. It all happened so unexpectedly that I forgot to do anything, so I turned around and drove back up to them and shot the biggest one.
My hog problem was pretty bad until Covid hit. One of the things that was allowed during the lockdown was hunting. A client of mine asked to shoot hogs at night with a thermal since he couldn't do anything else. That first year, he shot 140 hogs. The second year he shot about 40 hogs. Since then, he's only been able to shoot about a dozen or so. They have almost disappeared!!!!!
He has two feeders with game cameras on them. He sits in my deer blind and falls asleep. When a hog shows up, the game camera sends him a message that wakes him up. He shoots the hog, or hogs, then either goes back to sleep to wait for more hogs, or calls it a night. His very best night, he got 14. He had a few nights where he got 12. Right now, two in a night is a big deal, if he gets any. I'm lucky that he is totally obsessed with shooting them. He puts in all the time, money and effort to make it happen, and I get the benefit of not having a hog problem anymore.
My long term goal is to fence them out. When I bought the land, I thought that hog hunting would be fun. After shooting them, and my wife shooting them, we sort of lost interest in it, and decided that if somebody else wanted to shoot them, that would be great. This has turned into a big win for us!!!!
I still carry the pistol, but mostly for snakes. I used to have a bad snake problem too, but with a lot of mowing, and about 30 cats, my snake problem has been severely reduced. Worse year we killed over 40 snakes. So far this year, I've only shot two.
