This was the first model in the Schmidt-Rubin series of repeating rifles. They are easily recognized by their 30.7" barrel, 12 round magazine with cut off function, and rear locking lugs. Like other rifles in this series, they have a straight pull bolt, grasping knob, and manual cocking ring. These rifles are chambered for the 7.5X53.5mm cartridge. I don't know of a place that loads this cartridge, but it can be hand loaded using 7.5X55 dies and standard 7.5X55 brass. The brass must be trimmed to size and the proper diameter bullet used. A Google search should get you all the info needed. About 212,000 rifles were manufactured from 1891 to 1897 by Eidgenossische Waffenfabrik in Bern, Switzerland.
