A hunting show on TV recently featured pass shooting European wild boar from stands in Hungary. These were huge critters and the hunters were using .375 H&H on the beasts and it looked like fun. The lodge looked like an old castle and they were into some traditional type ceremonies.
Most wild hogs in Florida are 100-300 lbs, so they don’t take too much gun as long as you can get a decent angle. There are stories of big ones ( 400-500lbs) but I’ve never met anyone who actually saw one.
