Help Identifying Ammunition

[jester617]

Would someone here help in identifying some ammunition.

I purchased some Swiss 7.5x55 Ammo in chargers not to long ago. I was much more (only) interested in the Chargers, but the ammo was a bonus.

When I got home, took the rounds out of the Chargers and discovered the following:

I apologize for the crappy cellphone pics!

Not sure how to properly describe a head stamp. But at the O'clock positions 12-3-6-9 are the following:

4

S

24

D


They look like 6.5x52 Carcano. Any help would be appreciated.

Thanks. I did Google it, which led me to believe it was 6.5 Carcano.

I posted here in the hope that someone would confirm this and maybe even have knowledge of the head stamp markings as I have no use for this and did not want to list it for sale without more info.

If you have a micrometer, measure one and post the dimensions.

oh there ya go, that should confirm it. Even if you just have a good metric ruler it should be close enough

the headstamp isn't right for 6.5 Carcanno. Close to the 7.5 Swiss but I haven't found it. Closest I have found is 3 D S 24 which is a 7.5 Swiss

7.5 x 54.5 (55) Swiss according to the doc here: http://www.colcartinc.com/METCFR_0_to_7.6mm.doc

these have steel jackets and flat brass primers with black seal. See Datig 3-30

When were these made? I thought just about everybody (other than the Italians) went to spitzer bullets after/during WWI. Also I didn't realize that steel jackets were common before the commies started using them a lot.

Good question. That doc I found it in is from a "collectors cartridges and obsolete ammunition" site. I wonder if it's 1924 ammo based on the headstamp.

Later, in 1923, the GP1890/03 round was again modified. The new round, designated the GP1890/23 fired a 190gr CuproNickel Jacketed Lead round nose bullet and used smokeless powder. In addition, the round was lengthened to 54.5mm. The GP1890/23 generated around 37,000 psi. The GP90/23 round was available into the 1950s, and is the cartridge of choice for pre-1911 modified Schmidt-Rubins.

Swiss 7.5x53.5 GP90/23 for the 1889 rifle.

 

[jester617]

Yes. 7.5X54.5

 

[JuergenG]

53.5, really

 

[jester617]

53.5, really

Can you share something that's missing?
Your input would be appreciated!!!

 

[JuergenG]

The GP90 and GP90/23 measures 7.5x53.5mm

 

[jester617]

Why do they list the 90/23 as 54.5. Is that just to differentiate the 03 from 23 or a typo of some sort? And thank you for the info!!!

 

[JuergenG]

Oops, my bad. I mixed up the GP 90 & 90/03 (7.5x53.5) and GP 90/23 (7.5x54.5). Sorry!

 

[jester617]

I was hoping for an awesome story!!! I love my K31's and have a bunch of GP11. It's been interesting learning about the evolution of it.
