I guess a counter question for you hog man is are you planning on slug gun hunting or running dogs and using buckshot.

There are good and better choices for each.

If you are slug gun hunting, I'd recommend you spring the money for a rifled and cantelieverd barrel. If you are still hunting, this is obviously the best route. Don't know where you are from, but if you are hunting hogs (per your handle) there is a good chance that you can use rifles for deer and hogs in your state.... so I'm going to assume option #2....

For buckshot, there are plenty of good shooting guns. I grew up shooting deer in front of hounds... buckshot was a way of life... I'd probably shot 5 or 6 deer with my 20 gauge as a kid before I shot my first one with a rifle. I'd hate to think about how many I've shot with buckshot now.... dozens....

My buckshot gun is an 870 Wingmaster Magnum that is older than me by a few years. Gunsmith put chokes in it for me when I was 11. I shoot an extended Modified choke tube made by Briley. Its marketed as a waterfowl choke, which is kinda my thing in hunting, but it so happens that is shoots buckshot like a dream. A good friend of mine uses his turkey gun to shoot buckshot with. Its a Mossberg 835, I have one myself, but its just a turkey gun for me. The 835 has an overbored barrel, that makes the patterns very dense and even. Most hunters over choke buckshot, which is a mistake. Every gun is different and you have to expirament with yours a bit to find what works the best. Another great pump gun for buckshot is the Browning BPS, which is back bored, and is known for some great patterns as well, and is one of the better pump guns currently being made.
