I picked this up at a gunshow a while back, vendor had about 100 boxes but no info on original source. Markings appear GI to me, maybe for Armed Forces pistol team...?...

Actually its the other way around. Winchester is a division of the Olin Corporation.Definitely looks like gumm'nt packaging.
Isn't Olin the ammo arm of Winchester/Western?
What do the bullets look like? Lead? Copper-washed? Jacketed?
