Mystery Cartridge

[Michael J. Spangler]

Anyone have a clue what this is? I found it in with a bunch of ammo I picked up in an estate sale.




22 cal bullet
Base of the cartridge is .295" or so
rim is .350" or so

Almost looks like someone shortened a 22 hornet

Maybe a 22 flobert?

Centerfire or rimfire?

5.6 velo dog, maybe.

Not the 22 Flobert. Friend has one and the cartridge is not bottle necked.

Indeed it is. Its use for rook rifles etc. was uncommon and incidental to its main application, which was training with a subcalibre Morris tube in the Martini-Henry and British Lee rifles. were better rook rifle cartridges, and a .25 or .30 calibre worked better with black powder.

Those who developed indoor league rifle shooting in the UK thought it unlikely to develop sufficient accuracy, and went to the .22LR instead. It can be made from .22 Hornet, but is likely to require neck thinning.
