It appears to be a .308 with a small copper projectile. Headstamp has 5 4 K.

Nobody knows.

That's a real stumper. Has you confirmed it to be a .308 cartridge? Some low-power, low-recoil projectile for some purpose. Spotting? Training to duplicate a grenade launcher? Indoor range practice load?

Just guesses on my part as I have no clue.

Sure that is not a 6.5X55 training round?

The bullet is a little hollow cup.


Scroll to the bottom.
6.5 X 55 Ammo

Appears to be some sort of a training round. I've got a few boxes of 7.62x54r Russian training/practice cartridges that have bullets that resemble those very much. Can a set of dial calipers be used to take measurements to determine caliber and case dimensions for verification of cartridge determination. R.

Sure doesnt look like a 308 case.

looks swede

I think ireload has it on that link

This is from Matts Perrson's page. It has a lot of good stuff about the Swede Mausers.

More on 6.5X55 ammo

I had 100 rounds of that ammo I bought to reload with some Berdan primers.

ireload2 has solved it.

thanks.

In various european countries such ammo is/was used for Anti Tank Rocket Launcher short range practice training.
There is a french made ammo that is used in 89 mm AT weapons, that duplicates the trajectory of the rocket up to 75 meters using a lead round bullet in a conversion system.
