What is known about the 7.61x51mm APDS cartridge with Depleted Uranium core known as the D.U.D.S.? I know that specimens have a black sabot and the headstamp of “L C 7 0”, but that is about it. XM-??? Any other variations? Legal to posess in the USA? Successful but too expensive to manufacture?
On a related topic, was DU ever used in any other SAA experimentally or otherwise? The only other DU cored cartridge I can think of is the 30mm API used in the GAU-8.
