Savage's bolt-action shotguns have rifled bores and are meant only for slugs, typically special slugs with polymer tips. They're essentially extra large bore rifles, 20-Gauge and 12-Gauge, they have some popularity in states only letting you hunt with shotguns.
The box magazine holds 1 or 2 rounds I think, but most users complain that the magazine doesn't tend to want to work. Not a huge deal though since you're probably only taking one shot at a time anyway, and if you hit a deer with a 12-Gauge slug (which you're going to have rifle-like precision with here), you probably won't need to shoot it twice.
