Potential shooters will eventually realize that 12 gauge 00 buckshot will make for a far uglier scene
and then the Grabbers will go for shotguns too. Sorry, Slow Joe, Jill will have to just blast a couple rounds of spitwads into the air out their back door
IIRC, weren’t shotguns used by gangsters for massacres during Prohibition?
Possibly, but range is even more important than destructive power. The thinkers among the lefties are most worried about 10,000 snipers with AR-15s and similar than about shotguns which are not much good for sniping I think you will agree...
