On Armed American Radio last Sunday, Mark Walters and I joked about an Anti-Gun report that mentioned .22 Rimfire Shotguns. I was unaware of any such beast, as was Mark.
Well, Mossberg actually made one. I was looking up a source for a .22 Magazine and found reference to the 1930’s Mossberg Targo .22 Shotgun. So, I was wrong. There is a .22LR Smoothbore out there. These were produced until, believe it or not, as late as 1968 according to that link. Remington made one too. Based on their little pump action .22, it was called the MoSkeet Trap. These were primarily used in Shooting Galleries, but saw slow sales everywhere else.
So, there you go. I was wrong. I am however surprised that Listeners didn’t call this to our attention.
