I think John-Boy posted some loading data a while back.  He and I were both working with old Euro-schuetzen/stalking rifles in that caliber and we got a replica of the original stop ring bullet made for them by AA molds.   On first firing for fire forming cases I found that my firing pin hole needed bushing--rather badly so I sent it off and have not done anything with loads since.  But J-B worked up loads for his so a search under 9.5x47r should turn up the results.  
I think its basically a bottleneck short-body long-neck black-powder euro-version of the original 38-55.
