Original 30-06 ammo, Corrosive or not?
I found some original, still in the sealed boxes M2 Ball ammo for my 03A3. My dad had bought thousands of rounds of surplus ammo throughout the years and reloaded it as needed. These were in an ammo box that was either forgotten or just never opened after he bought it. the boxes are marked BALL
Caliber 30 M2
Ammunition lot U
16506
The head stamp on the rounds is U and 42.
