When talking about what type and length of barrel for a .32 think about the weight. A long, straight octagon barrel in .32 can be pretty nose heavy if it's more than 3/4 inch across the flats. That's a mighty little bore with a lot metal around it. Some shooters like a lot of weight up front, but I like a better balanced rifle. Also, for some of us old guys it can make for a heavy rifle that's no fun when carrying it in the woods all day.
I'm in line with the English Rook Rifle suggested by Bob Roller and Tom and I'm currently gathering the parts for one myself. A shorter 3/4 inch swamped barrel in .32 inch caliber, as Tom suggested, should make an nice half stock squirrel rifle as would a tapered barrel. I'm going to use an Oregon .32 caliber, 28 inch barrel tapered from 7/8 to 3/4 in my English Rook Rifle. It should be a nice handling squirrel rifle I can hobble with through the woods all day.
Florida is one of the minority of states that allows .40 caliber rifles for deer hunting. That's probably because our white tailed deer aren't very big. It's certainly a lot more rifle than is needed for small game hunting but will work okay if you're careful about where you hit them. I'm going to be hunting deer this season with a .40, but I'll let a big wild hog alone when I'm hunting with it. I've been treed by a big boar hog in the past and I don't want to do that again.
