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.

this going back 20 some years ago I remember seeing Dutch or Norwegian 9mm ammo in wood cases at a gun show, stencil on it was +P+. and also written on it FOR USE IN MACHINE GUNS ONLY

As for the 100gr Hirtenberger ammo, that's a pretty light bullet for 9mm, and with that, the powder is typically increased, giving way for higher Copper Units of Pressure (CUP) which measures chamber pressure. Light bullets always have more powder charge than heavy bullets - that's just how it is for both handgun and rifle cartridges. With a lighter bullet, the speed is always faster than heavy bullets. Trust me, I've been reloading since the mid 70s and have loaded several hundred thousand rounds of different calibers from .25 ACP up to .44 Mag and .223 up to .300 Win Mag. I don't shoot light bullets much anymore, not for the fact that they piss away more gunpowder, but just the noticeable case bulging near the base; plus I don't beat the crap out of my guns with heavier bullets/less powder charge. If you shoot 9mm in a fluted chamber and the brass tends to extrude into the fluted 'splines' (like below), 'probably should not use that ammo, or if 'rolling your own', back off on what the loading manual shows 'maximum' charge.

That is EXACTLY what I experienced with the corrosive Israeli ammo I purchased 20 years ago.....along with
a few other things. And yup.....it was 9MM too. As the saying goes; "If it sounds to good to be true....."

Thanks for that!!!!!!
