Direct Copy of translation by R.A. Steindler:

>>At the end of the proof load tables there is yet another listing of five re-enforced proof loads for rifled barrels, in this case Express barrels based on the same system. We list but a few of these tables here for comparison, and the difference between smoothbore and rifled barrels in the same caliber or bore diameter should be noted.


For calibers not listed in the proof load table, the person submitting a gun for proof must furnish load data in writing , as well as suitable cartridges, free of charge, to the proof master.<<

Also, remember that the proof facility would proof the tube with the largest cartridge that would fit the chamber.


Hochachtungsvoll,
