Age old question about RFI .410

[Aragorn243]

The original was for a specific brass cased solid lead ball cartridge loosely resembling a 410. Ammo not readily available in the US so many importers altered them a second time to the 410 shot shell. And now suddenly the original ammo is all over the place and dirt cheap. Mine also has been reamed out for the shotshell. Pretty sure it also will handle the 3 inch shells.
