Does anyone have a good load for 8mm Mauser using Sierra 175grn spitzers? I have been using IMR 4064 to load some 30-06's but will get a different powder if needed. Most of the reloading data gives what appears to be some very light loads. I'm talking about 2200 fps with pressures around 37,000 CUP. By the way, I'm shooting a 1941 bcd rifle that appears to be in very good condition. I'm just getting started in handloading so any information shared will be appreciated and put to good use. TIA, Ben.
