You can still buy the Marlin 410 from Cabelas. A fun firearm for small game, varmints, pest control – DEER! Patterned after Marlin’s exceptional 1895 rifle, this .410 bore lever-action shotgun sports a 22″ blued barrel, a handsome walnut stock and a tubular magazine. It fires a 2.5″ round only. We have tested this 410 Marlin shotgun with buckshot, pumpkin balls and slugs: Slugs and pumpkin balls are best. As for birdshot, it is a cylinder bore and therefore your patter is dispersed quickly. You could kill small game effectively to 20 yards with special handloads.

why is a 410 a shotgun and not a rifle!! i have heard both can you please clarify!! irreshbrewer6969@yahoo.com!!! please respond!!!
Because it has a smooth bore (no rifling) and is designed to be used with shot shells at short to intermediate ranges (10ft to 50yds)
