All Austro-Hungarian pre-WW1 smokeless ammo was of infamous quality. Main reason: They had a government monopoly on powder! Only one government factory smokeless rifle powder was available, named "Pulver III" to the private ammo makers Roth, Hirtenberger, Sellier&Bellot and so on. This powder was fast and erratic burning, variing from lot to lot. Smuggling in German made powders and cartridges was a favourite pastime of sportsmen travelling to the vast and wild hunting grounds of the double monarchy. Bell also reported problems with signs of excessive pressure when using Hirtenberger ammo in his 6.5x54 M-Sch carbine.
