.22 Johnson Spitfire perhaps or a variation thereof.I purchased some brass recently and there were 50 Primed cases in a box marked 22 M1 WK
Internet search didn't yield anything.
The trim length is 1.179" and the neck length is about 0.185"
Anyone know this cartridge?
Agree with the spitfire..22 Johnson Spitfire perhaps or a variation thereof.
The print that I saw on the 5.7mm/22 Spitfire shows a base to mouth length of 1.290" and a neck length of .220"
