Hi,

Hirtenberger is an austrian manufacturer, but no longer in business. They were taken over by a multinational RUAG Ammotec in Switzerland. They produced ammo since I don't know when, motly high quality, but I remember my Colt Combat Gov't from 1986 didn't like their Hardballs. My S&W M27-3 really likes their .38 Special 148gr WC and produces groups under 1,5" at 25 meters (I still have about 1400 rounds, then the supply i finished) - their brass is excellent for reloading, the strongest cases I ever had....

best regards
Ulrich
