As far as deer hunting goes I wouldn't get one until they force you to. And then most modern inlines are actually a bit better in my opinion. I own both, and while I love my H&R ultra slug gun, my Muzzle Loader is actually more accurate farther out and was easier and cheaper to get that way.

Slug guns are easier to shoot and maintain, but the premium saboted slug ammo is EXPENSIVE! Like 10-15 bucks a box for 5 rounds.

If I didn't have to use a ML or shotgun where I live I would have a 30-30 or 243 within a month of the regulation change, even if I had to sell my slug gun and muzzle loader to get one. I still have 3 other shotguns for small game and bird hunting.
