Ok..

That is dezincification...!

The cases have been stored in conditions which have lead to the zinc component of the brass being leached out. It effectively weakens the structure of the brass making it brittle, resulting in case failure. The linear failure lines indicate that the rounds have been lying on a damp acidic surface and are typical of those from wet cardboard.

ANY evidence of tumbling of loaded ammunition is an indication that it is in a dangerous condition and should not be used. Aircraft ammunition subject to vibration suffers from the same risk and is given a restricted life for that reason.

Bruce's observations on mercuric and chlorate primers are also relevant, but in this case it is the state of the case material and the propellant that is the limiting factor.

As an Ammunition Technical Officer of over thirty years experience, my view is that this ammunition is not safe for use and should be destroyed..
