1050 question

[Zamble]

Last night I was going through .40 brass, decapping/resizing them for a friend. It was the first time I had done .40.

We noticed it was a hard pull occasionally. After maybe 50 pieces, we started checking out the processed brass. A couple of them still had their primer in them. The sewage had packed it in. That was the hard pull.

So I started watching for the primers seeing if they were being removed. When it advanced, I pulled the brass out to look at, before swaging. Sure enough the primer was just barely hanging on in the primer pocket. I would just touch it and it would come right off.

So I got down and watched it while it was resizing and depriming. I could see the decapping pin go through and remove the primer. On the way up, I could see the primer come back up on the pin and barely go in to the primer pocket. Hence my problem.

Is this common for .40 on the 1050? Or am I missing something. We ran a bunch of 9mm and didn't have a problem.

Yeah I had this. Polished and rounded the decapping pin point and problem went away.

I had this happen on a single stage. Fix was two-fold. Lower the pin to be sure the primer is all the way out of the case. Polish the pin so the primer doesn't want to stick

The pin goes all the way and beyond. Ok, I will try to polish it.

Yes, its just the decapping pin getting stuck on the anvil of the primer. The primer gets pulled back up into the pocket and hangs up things. Changing the profile of the pin just a little usually does the trick. I blunted my 9mm decapper just for this problem. It is a Hornady die. My Lee universal decapper never does this.

Dillion dies? They will replace the decap pin. It should not be doing that. I'm betting you are using an RCBS die since they are the only ones I've seen behave that way. If so sharpen / polish the decap pin.

Dillon pistol dies have a spring loaded decapping pin that "throws" the primer off the end of the pin after the primer is out of the primer pocket.

Actually, I only use Dillon dies on my 1050. The dies are brand new.

Call Dillon, get a new decapping pin.

Randall, this is only on the new dies right? I don't think the older ones did. Perhaps the OP has an older set.

Or just get the 10 pack of replacement decapping pins for like 5 bucks. You'll need a spare eventually

Be careful the heavy pull will eventually break the swaging rod

If by "new", you mean since the mid 1990's, yes.
The "old" dies would be the ones made from the 1980's to the mid 1990's.

>The sewage had packed it in

What? I assume it is some typo and you don't really have sewage packed in something.
Why do I only read about this problem with Dillon dies?
There should not be any crimped primers in .40 S&W cases, but stranger things have happened.
I don't care much for the Dillon dies I have, but mine never did this--but I sure read about it a lot.
Definitely call Dillon and get new pin(s) or flatten the tip and bevel it (or whatever folks have found that works).

PS: Why call this a 1050 issue? It is a Dillon sizing/depriming die problem that is independent of the press used.

Swaging?
