Hey curious if any one can tell me about their experience using hirtenberger surplus ammo ,7.62x51,in their hunting rifle. The stuff I have is marked with HP-75-11(it looks like a 11). Has red coating on primer .
What does these markings mean. Is berdan primed a harder primer then boxer primer?
I've heard some surplus stuff is said to be non corrosive but actually is slightly corrosive .

Clean burning. Very little copper deposit
Shoots at about 2700 fps from a 24" barrel.
Several accurate heavy barrels ( rem police, kimber Longmaster) shoot it to 1-1.5". No better, not worse.
Lighter barrelled guns ( rem mountain, model 600) shoot it to about 2"
Speed difference is 50 fps or so.
Cases (boxer) reloadable, brass has greater capacity compared to lapua.
Brass is soft. Ejector marks common on loads that are within pressure on other brass. Trimming required after each reload so far.
Zero misfires.

The headstamp of HP means HIRTENBERGER PATRONENFABRIK
The 75 is the year of manufacture. Mine is stamped 83, boxer primed made in 1983.
The II is common on all of this ammo
Some of the berdan primed stuff was reportedly very hot, but I cannot comment as the rounds I have are not.
 
Corrosive ammo with this stuff is never an issue ? Or do ppl treat it as corrosive ? It was made in 1975 :s

The Hirtenberger is not corrosive. Don't know of any 7.62x51 NATO ammo that ever was. The NATO countries stopped doing corrosive ammo, for the most part, after WWII, and 7.62x51 wasn't introduced until the mid 50's.

IIRC, it's actually part of the spec that it be non-corrosively primed.
