Buy a Lee .30 Luger "factory crimp" die (Midway USA Product #: 163481) and your troubles will be over. The "roll crimp" is very hard to get working in auto pistols, especially those under 9mm. The Lee crimp die uses a collet to convert down force to side force, and the collet can break, so tighten down slowly a bit at a time. I use mine on my 7.63mm Mauser, and it works great.
