I have a Marlin 512 Slugmaster. It shoots very well and I've taken a pile of deer with it. They are no longer made but can be found used. Same goes for the Mossberg 695 (I think that's the model). Both of these are kind of bulky. My 512 is like a 2x4 with a steel pipe bolted to it.

I really like the savages, and if I were to buy a new gun, I'd go with the 212. With the sabots available today, the 220 is very capable as well.
