Occasionally spits a primer out of machine?

So I ran a thousand or so 45 auto large primer today with Winchester primers. Twice I heard something land on the bench, a live primer, and upon checking the case at the powder station has no primer.

I had this problem once before when a friend was using up some very old CCI primers, and I ended up tearing it down for cleaning and inspection, but I couldn't see a problem or how primers are apparently escaping.

Ideas?

The most likely cause for this is an eccentric primer fails to drop into the hole in the primer slide, and it gets swept off as the primer slide moves forward. There are two debris holes in the primer slide channel that the primer can fall out of.

Thanks for the reply. I thought cleaning the unit and running Winchester primers cured the problem, but apparently not completely, though I did run the machine today with no issue.

Is there a solution? I was considering polishing the hole in the slide slightly.

I would advise against polishing the hole in the primer slide unless obvious wear or damage is visible. Do push a small patch wet with alcohol through the magazine tube several times to clean it.
No brand of primer is immune to out-of-round primers.

I've had to clean the inside of the primer magazine, and the tubes for my rf 100 a couple of times. Maybe I need to do that more often.

Anyway, thanks for the help.

I'm having the same problem...the S1050 is brand new. Probably had 10-12 new primers spit out during the 800 rounds I loaded. One was crushed and I'm glad it didn't go off!

Did they spit out consecutively, or randomly?

I’ve had my Dillon 1050 for 2 years now and it’s been largely problem free until the last couple of weeks.

I don’t shoot or load nearly enough to justify the 1050, but I treated myself to it as a retirement gift.

Lately, I’ve had the same problem, where multiple primers having streamed out all over my bench. I’ve even had a handful spit into areas where they went boom!

I contacted Dillon, but and they suggested changing the tip on the end of the magazine, which seemed to help the problem.

I decided to switch calibers from .45 to 9 mm, ordered the conversion set and small primer setup. Same thing happens now with the small primers, but many more of them spill out.

One must have gotten lodged in a place it shouldn’t have and kaboom, castrophoc boom. I blew up the inner magazine, destroyed the primer alarm and shot the following rod into the ceiling, as well destroying the primer alarm.

I’m super scared of this thing now and will call Dillon first thing in the morning to plead for help and order new parts.
