I am currently looking at two mold designs from Accurate Molds. I am trying ti balance practice vs serious use. My plan is to use 40cal brass for practice/playing IDPA and carry 10MM brass for serious work using my GP-100 revolver.
The only parameters at this point are the design has to be plain base. I have a Gas check maker from Pat Marlin and intend to apply GC's tp the base of the bullets most of the time. I will be sizing the bullets .401. I will be asking for a min diameter of .402 using WW alloy.
I am looking at two designs right now. the 40-215F and the 40-189B. Not sure if these are the best two and would appreciate any thoughts you guys might have.
