Daryl, if my 9.3x57 can duplicate 9.3x62 ballistics at <55000psi I will be quite satisfied. I also plan to develop modern loads for my 8x57IS and newly acquired 8x64S. The Mauser cartridges are in FN 98 Mausers with 3.3" mags and the 8x64S Brennecke is in a BRNO ZG47 with a 3.46" mag.So I can seat the heavier bullets flush with the base of the neck.
