I am beginning to study up for loading 8mm Mauser JS(.323 diameter). Using IMR4064 I have noticed that most reloading manuals start loads are around 35 grains powder for a 170 gr.SSP(+-2000 fps) while the Speer manual starts at 45 grains for (+- 2500 fps). Is this because of a fear of liability issues of someone blowing up a turn of the century Mauser(.318 diameter) or is this a case of Speer loads starting hotter than others just because? All opinions/advise appreciated.
