11x60R Mauser ammo mfg 1883. 1000 rds all fired with one hang fire. Beware of WW2 German ammo that has steel cases. Sometimes the case rusts from the inside out and catastrophic case failure can occur.

Corrosive priming has an unlimited shelf life. Non-Corrosive priming about 40 years. Our club has LC .30 M2 Ball that was made in 1966. It all fires.
