Weird 9mm Ammo

[Guest semiautots]

I picked up a case of this stuff many years ago.  Anybody know anything about it?

 

It's in a green British ammo can, as issued.

HAZARDOUS AMMUNITION

Washington--The Bureau of Alcohol, Tobacco and Firearms (ATF) has been advised by Hirtenberger AG, Hirtenberg, Austria, that certain 9Xl9 mm
caliber ammunition produced by Hirtenberger is unsafe for use in any handgun.

The ammunition, designated L7A1 and produced ln the years 1990 through 1992, was produced for the British Ministry of Defense specifically for use in submachineguns under adverse conditions. The ammunition was loaded to produce pressures far in excess of that intended for use in handguns.

The manufacturer advises that up to 12 million rounds of this ammunition has recently been sold on the world surplus market. The ammunition can be identified by the following head stamp located on the bottom of the cartridge case

12 O'clock position: HP
3 O'clock position: 90, 91, or 92
6 O'clock position: L7Al
9 O'clock position: the marking of a cross within a circle

This ammunition should not be fired.

We are not aware of any of this ammunition being imported into the United States. ATF will take action to prevent the commercial importation of this
ammunition.

For additional information, contact, Mary Jo Hughes, Chief, Firearms and
Explosives Imports, (202) 927-8320. "

If you don't want it, I'd be happy to take it off your hands if your giving it away. I have two MP5's that I'm sure would love it :)
