Well, not really.
Was just given a opened box of 30/40 Krags. The strange thing is that they are all nickel plated including the bullet! Bullet non magnetic.
The box says, Ball Cartridges---Caliber .30. Powder WA Smokless Primer G.36.
Usual directions to throw empty in water.
Manufactured at FRANKFORD ARSENAL.
Most of the cartridges are marked:
12:00--F
3:00--98
8:00-- 9
Can post images later if needed.
