World War II 20mm Naval Ordnance

Hello Forum, New member with some ordnance from wife's uncle, Navy Warrant Officer on PT Boats. KIA 12/30/1944. Unsure if they are armor piercing or tracer shells.

Welcome to the forum. They look to be 20mm Oerlikon.

Thanks DD. That is one "beast" of a gun

The holes drilled through the cartridge cases and the absence of a primer indicates that these were inert, dummy training rounds, not AP or Tracer.

 

HTH.

 

Regards,

Thank you Mr Flick. They are stamped 1944 and 1942. The different colored head was why I thought they were AP or Tracer. Appreciate you input
