US Military 22 rim fire cartridge

[RCS]

Found this among my few 22 rim fires, it is the M24 full metal jacket 22 rim fire45750

[Fred Pillot]

Crazy, any idea what it was for?

[RCS]

It was issued for survival rifle/shotgun combination weapons. They (military) needed a full metal jacket and could not
use a lead bullet. I am sure there might have been other applications for the cartridge in the military

I know this is an old post, but the Army had a .22 barrel insert used to qualify with the M-16 in locations without a real range. A little off topic but they also had an insert for the 4.2 mortar that fired 60 mm mortar rounds and one using compressed air that could be fired in a big building.

M261 is the M16 kit,

they work well, just replace the BCG

but only works Semi

10 round mag that inserts into the original 5.56 mag

Very strange to see a heeled FMJ bullet.

Somewhere in my plunder I have a box of military .22 Hornet soft point ammunition. It has a warning on the box not to be used against enemy combatants.

used to have one of those survival rifles in the shop,
had to Form it, since the barrel was less than 16"

neat little rifle, don't see them too often
