For firing slugs in an unrifled (smoothbore) barrel, what do I look for in a purchase of a box of ammo? I just picked up my first semi-auto, an 8-shot Mossberg 930 SPX, which will only see buckshot - other than slugs.

Foster style slugs out of a smooth bore is relatively accurate.

How do I identify a "foster style" on the box?

rifled slugs

If it says "sabot" anywhere on the box, avoid it. Those are for rifled barrels.

Rifled slugs are for non-rifled barrels (smoothbore).

If you look and the end of the loaded round and see unjacketed lead, either round nosed or hollow pointed, you should be good to go. If you see something that looks copper plated or jacketed, you are probably looking at a sabot slug that will not shoot accurately out of a smoothbore beyond about 10-15 yards.

Rule of thumb- either the bore or the slug should be rifled. Not both. Not neither.
