Hello,
Why not just cast up some hard balls?
I have some really hard ones in .440" and .490" that are 90% lead and 10% Linotype. They feel like steel ball bearings. I'm not certain they'd flatten at all.
The others I use are made from 10:1 lead/tin, no antimony. I prefer these for general shooting and while they should expand in game, they won't flatten as much as pure lead, and should still punch through-and-through pretty much anything.
If I were going hog hunting, I'd use the Linotype hardened ones. I'm sure they'd punch through the gristle shield.
Coyotes don't take much killin'. I use a .22LR and take them cleanly - or used to. I have trouble on the trigger now. I had a wolfdog (mostly wolf) for a year or so, currently have a very low content wolfdog who is my best friend, and have come to know a coydog very well. He resides at the local gunshop. Very intelligent creature and, while shy, he comes running to me before anyone else when I walk in.
I'm one of those folks who knows how to communicate with these animals. One of my other hobbies.
But last time I went coyote hunting, I had trouble on the trigger. Tika, Nikki, and Bear all kept flashing through my mind.
But I digress.
You hit a hog with a .36, especially if it's a harder cast, and it will punch through to the vitals. Might keep a Navy on hand (don't try to load this with anything but dead soft lead) for backup, but I see no problems.
I am actually looking forward to this. Hogs have penetrated into Southern Indiana; I know some folks who have take 'em. They're moving north, and I have some prime deer habitat here that hogs will root up. All arms will come to bear in that case. I'll be trying to cull them out faster than they can breed.
