You're thinking about the latter made Fox double barrels. The earlier 1s were better before Savage did their thing. They're fine to shoot LEAD shot out of. Your dad would scold you for not taking it hunting and thus carrying on the tradition.

The Fox Model B was not a particularly high quality shotgun, but they were made with very good steel in the barrels. They are safe with any lead shot shell of the length stamped on the barrel. It was made by Savage Arms, and is pretty much a gussied up Stevens 311.
