Damaged shellplate

#1 · June 9, 2008, 3:30 pm

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?

phone us for a warranty replacement shellplate.

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.
