Mauser chambered two. The 6.5x57 and a Short case for short actions, I don't have my resouces here with me (I'm on business in Italy), but I think it was 6.5x51 or maybe shorter. The case is made by resizing eithe the x57 case or the 6.5x54 MS. Look at Cartridges of the World. It will have the info on the short 6.5. The ballistics are about the same as the 6.5x54 MS.
Sorry for the vague references.
