I’ve got a bullet that I found at a WWII Army Air Corps training base years ago. It is just the bullet and not the entire cartridge. I measured it today and it is .43" (10.9 mm) in diameter and is 1.85" (47.1 mm) long. It looks just like a smaller version of a .50 bullet found at the same location. Does anyone have an idea what this is from and what weapon used it? I’ve done a bit of searching on the web but haven’t come up with anything.
Thanks for any information.
