I am loading 9x19 and have a question about crimp and headspace. I'm using a taper crimp die but how do I know when i have it right? I adjusted the dies with a factory round in the shell holder, then loosened it up a 1/4 turn. The resulting loaded shell would not chamber properly in my pistol. I adjusted the die until the shells would feed reliably, then tightened it an aditional 1/16th of a turn.
How do I know the headspace is correct and it is not he extractor holding the casing against the bolt face? Is there a standard loaded case mouth diameter? I could find OAL in my manuals but not that information.
