I have two more rounds without a definite identification. The first is a 25x110mm rimed case with an armor piercing solid steel projectile. It has a groove around the cartridge case which I am thinking says it is a practice round. There are no markings on the projectile or the case. The second round is all aluminum with a steel insert. The marking on the projectile is MANIP. PATR., which I understand. Is there a model number to it and what country made it? My dimensions may be a little off.

Hi Bob, I can't help you with an ID but just to confirm I used to have an identical 25x110 round, same case type (but tarnished a lot more), same style primer, same projectile, same groove around the case, also no markings.

Interesting cartridges.
Can you give any or all dimensions of both rounds?
MANIP. PATR. could possibly be Swiss.

The second round looks like a 24 x139mm Manip. Patr. dummy for the Swiss Tankbüchse 41 antitank rifle.
