The CMP will occasionally sell it when they get it. "Lake City" ammo is the term, I believe. It's American manufacture, dunno the date. Google "surplus ammo;" there's a bunch of other websites which sell surplus ammo. I have heard tell, though, that some businesses will buy the max allowable through the CMP and then turn around and sell the same rifles/ammo at a markup . . .Ya, thats the M2 Greek Ball, I believe. My buddy has a few Spam cans of the stuff. Looked to be in rough shape, but ran like a top.
I was wondering where you could find the American-made stuff from WW II/Korea.
