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.
