The barrel is rifled. Smooth bores must be > 18", even T/C's. This ruins the shot pattern, but makes them legal, without licensing that is.Just curious, how do these skirt the minimum barrel length for shotguns?
Mr. Mysterious, The .410 is measured by caliber and not by gauge so technically it's not a 'shotgun'. That's the simple answer.
So I could take a rifled slug barrel cut it down to below 18" and make a Bonnie and Clyde shotgun and it would be legal because it is rifled? That just kind of seems like a gaping leap hole.
Well the slugs are generally rated at 1/5 oz.(~90 gr) ay 1800 FPS from a real SG. I've seen reports that from a derringer they measure ~1000fps. That puts it in .32 ACP territory.Will that thing take 3 inch shells? How does the .410 stack up in terms of stopping power compared to the 45 LC?
