Just scored a handful of these rounds. They need a bit of cleaning up but appear to be the real deal by the markings.

They appear to have been stripped out of some sort of link in the reasonably recent past. All I know is that this round was primarily used by the IJN on ships and aircraft, and to some extent by their "Marine" ground forces.

Interesting twist to my normal .303 scrounging.

In the same "bundle" was one FN-50 .303 with red primer sealant and a couple of 7.7 Jap rifle rounds that look like they have been in a VERY wet place, but might clean up OK.

Could be onto some Italianicon WW2 7.7 Rimmed ammo as well, just to make it "interesting".

This could be the start of yet another fascinating side-track!
