Hi all,
I have a used Pro 1000 with a #19 shell plate for 9mm/40S&W. I am sizing and priming off the press so that I can expand/charge, seat, and crimp on the press. Doing it this way has relieved any headaches I have encountered with the Pro 1000 priming system. All that said, the press loads 40 beautifully. But because the shell plate was made to fit 40 and 9mm, the 9mm being smaller rim diameter it doesn't work so great. My problem is that when the case enters the expander plug, it isn't always straight. If it is off center, the case gets smashed against the plug. I can guide it in with my finger, but it is very tedious and makes the whole process cumbersome and slow, exactly the opposite of how a progressive press should work.
I have read and seen videos of a #6s shellplate (for 32-20 and 25-20) being used for 9mm on a loadmaster to prevent the problem of primers not seating centered. I was wondering how well or if this would work at all on a Pro 1000. I realized that my problem is not with the seating of the primers, but if the 9mm case fits the #6 shell plate better, perhaps it could remedy my case alignment issues with the expander plug. I know that the rim diameter of the 32-20 more closely approximates the 9mm than the 40 does, but the rim thickness is larger than 9mm and 40, so I don't know if the tradeoff would be worth it. Any ideas?
