One of the carcano cartridges?

I've thought of that too

Nah, Carcano is 52mm

would be shorter

True

and being 6.5 would probably be visible difference

I'd want to stick with the swiss assessment

Rape

7.5 French is also x54

There's also 7x57 Mauser

And 7.5x57 French

7.5x54 French is updated from 7.5x57 MAS

Looks like 8mm to me though

@ϟϟGrafZeppelin'sLewdDefenderϟϟ 8mm Turkish

Need better pics

One sec

Possibly Yugo

There's 8mm from all over the world

Sending some more pics

7.92x57 "8mm" seems likely

Def Turk or Arabic

Don't use it in a semi auto and watch for hangfire but it should be fine.

Noted

Would it work in a G98?

The 7.9 is 7.92 (8mm)

I figured it was an 8mm

I should've grabbed one of the brass stripper clips too

If it's older it should use m88

1903 was when it switched to 8mm

One I was looking at was a 1914 spandau

So it should be fine then

Worse yet alot of original guns are rechambered for 8mm

And the markings conflict

That should be gtg in a 1914 provided it isn't badly reloaded

Stick caliper on projectile to make sure it isn't something else

That case looks pretty bad

The little Turkish crest is squashed so it's either been fired or reloaded twice or it was just a weak stamp

I see

What diameter and length should i check for on the projectile?

Just check to See that it's roughy 7.92mm
