the Hirtenberger ballistic must have been in the older Frankonia catalogs, think it was in itup to 92/93. the Hirtenberger load was very late and short lived and I think it was not made before 1985. before there was only the Kynoch softpoint load http://egun.de/market/item.php?id=5519794 available into the 1970s from old stock.

It seems Sellier&Bellot was making hunting ammo also in the 1960s

here is surplus ammo for sale
