Damaged shellplate

I reload 9mm luger with my SDB. After a couple of thousand reloads one day on the up stroke of the lever a case was not pulled out of the sizer die. The rim had been sheared off on one side. On inspection of the shellplate I found that a small piece of the rim had broken off. I got a replacement shellplate from my dealer and I thought it was a one off problem and it was solved.

Now, maybe 500 cartridges later, I have the same problem again. I'm starting to wonder if I maybe have a problem with my SDB. All the adjustments seem OK, my brass is clean, the sizer die and the shellplate are the correct caliber.

What can cause this problem?

A new shellplate is already on it's way via Dillon Precision Netherlands. I just wanted to know if you have any idea what could cause this problem.

Some brands of brass have a thinner rim than other brands. These can try to pull out the top of the shellplate, causing the damage.

I also reload the 9mm luger with the SDB and I have done so for over

10.000 rounds, never had a problem. The only problem I have now is a worn

indexing lever (wich,as we speak, is being send to me free of charge).

It might not be solving your problem, but it says a lot about the Dillon service

One question I would have about your problem is do you use any case lube on your brass before reloading? I was loading 9mm with a friend and we had that problem twice in a short time span. We thought maybe a different caliber brass had gotten in the mix but then he realized that he hadn't used any case lube yet. After that there weren't any problems for the next 500+ rounds that we loaded that day. (And thankfully there was no damage to any part of his SDB either)

We suggest lubing all brass, even with carbide dies. With a carbide die on a straightwall case you won't generate enough friction to cause a case to stick in the die; a little bit of lube goes a long way to reducing the effort needed to resize a case.
