I couldn't find this anywhere but if a dupe.... I haven't seen it.

Interesting idea....... I would never have thought of it.
I'm not sure it would cycle in a pump but it seems effective in a double.
That guy has immortalized some of the dumbest "gun store bull****" I've ever heard with his YouTube channel.
Historical side-note: (And if it's mentioned in the video, my apologies...I can't view it)
Cut shells were "developed" way back when shotgun slugs were A) rare, and B) very very expensive. Think Great Depression-era.
It was the poor-man's slug to be used for deer hunting. And it worked. Still works.
