20mm Unknown Projectile


#1

Can anybody identify this 20mm projectile? I have two the same.
Looks like someone has removed the cap from the nose?
Steel driving band. Tracer cavity is 33mm deep. One has a brass plug.
Both are 76.2mm long.
Both are stamped: 146 304 10

Which 20mm cartridge? Manufacturer & country?


#2

Markings and iron bands remind me of post war Oerlikon / Rheinmetall types(AA/AT).
Definitely looks like the windshield has been removed,possibly to remove the I from API?.


#3

The driving band is not steel but most likely sintered or soft iron.


#4

Are you sure this is 20mm?.
The images match the RARDEN 30mm L5 APSE projectile,minus windshield.

No mistake- it is a 20mm projectile. I was hoping the print and shape would make the identification easy. I hate finding damaged items. Ron.
