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.
The Russian hogs in E TN get to be that size...There are a lot fewer now than when I was hunting them in the 70’s....
Someone ran into and killed a really big un about a mile from me. This is the Florida Panhandle and you are generally right but the one I saw probably went at least 600 pounds.
It might have been a farm raised one which escaped and got larger.
