Remington .22 Extra Short Rimfire?


#1

I know Remington made the .32 Extra Short RF for use in the Protector Palm Pistol, however did they also make a .22 Extra short version.?


#2

Would that be a .22 BB or CB rimfire cartridge?


#3

Seems to be a slightly longer case. I’ve asked the owner to provide photos and dimensions.
I’ve seen the cartridge, it headstamp is U and it has a copper case.
I’ll post the details when I receive them.
Thanks
John
