I use a relatively light load of HP-38 powder (just enough to cycle the action). I bought two sets of .30 Luger dies- Lee and Redding. Brass is hard to find. I began loading with 86 grain soft point bullets meant for the 7.63 Mauser until I was able (through the good graces of GT) to get some really nice Swiss 93 gr. FMJ bullets. I love shooting the .30 Luger even more than the 9mm.
