I was trying to load my first batch of 9mm this afternoon, and hit a lot of trouble with my die adjustments. Prior to setting up the powder measure, I set up the dies to make perfect dummy rounds. Then, once I started putting cases into the press (Hornady LNL AP, Hornady dies) my OAL's were coming out too long, and the taper crimp die wasn't getting the job done. It was almost as if the press wasn't going all the way down, even though I made sure that the handle was completely pulled down. I was in the process of readjusting the dies to seat and crimp a bit more when I ran out of time.
I remember reading somewhere that the 9x19 is not a completely straight walled case, and that they might need a drop of lube, even in a carbide die, to make the process go smoothly. The sizer die definitely feels different than my 357, 40, or 45 dies, as it seems to stick just a bit on extraction. Do other people experience that?
I am using once fired (by me) CBC Magtech brass so far. The CCI 500 primers go right in, no problem there.
What is the best solution? Do I just need to keep increasing the amount of taper crimp until they all come out right? I have had similar issues in other calibers with the seating die needing an extra .003" or so when all the press stations (especially the sizing die) are being used, as opposed to running one case around the stations at a time. But in 45acp and 40S&W the taper crimp did not need readjusting. It looks like the 9mm does. I also think I might even have to increase the amount of case mouth expansion as well. The 9mm definitely feels different than those other calibers.
