You could easily use any load for the 9.3x57 & likely increase them by 5 to 10% due to the greater expansion ratio of the larger calibre as well as the 9.5x57 ctg. case which also has greater capacity than the 9.3x57. Starting with a 9.3x57 load of 48gr. H4895 with the 250gr. bullet would be a good place to start, but it will be fairly light load for your rifle. I used 48gr. in my 9.3x57 with a 270gr. Speer bullet in a model 96 Mauser & it produced only 2,268fps with ZERO expansion of the web of the case from being full length sized.
