I have tried to locate some information on the 25mm PGU-20/U API cartridge, however there is shockingly little on the internet. Here’s what I have found:
– Navy used in past
– Marines use (used?) in GAU-12 gun in AV-8B Harrier
– 150g DU penetrator
I would like to learn more about this round so if anyone has links, pictures, diagrams, cutaways, etc., please add to this thread.
Also, I would like to find an inert cartridge (or fired shell) for my collection (please PM me if you prefer not to post that info) so any suggestions on that would be appreciated.
