Unable to seat primers with Lee Classic Turret Press

Here is the situation. I use the press for batch reloading. I have been doing this with this press for many years without any problems.

Today I was depriming, resizing and seating new primers for .38 special. I do not use the Lee Safety Primer Feed. I just place one primer at a time in the cup in the primer arm. After about 30 cases had gone through I was not able to seat any more primers. I removed the shell holder and primer arm and it all seemed okay. For whatever reason, the base of the primer cup was not being pushed up to seat the primer. Yet I was able to do this manually when I had the primer arm removed. Whatever actuates this in the press was no longer functioning. I hope the problem has been described clearly because I need an explanation and some help.

Thanks for asking our advice

Not sure I understand completely, but I had a problem that might be related to yours.

The priming arm was not moving into the proper position when the ram traveled to the bottom if the stroke (to seat the primer). The primer remained in the priming arm cup.

Here is a temporary fix and diagnostic test all rolled into one.

As the ram moves downward, push the priming arm into position with a thumb or finger. Does that allow seating the primer?

Also. Is the slot in the ram aligned properly, placing the priming arm in line with the little bumps in the press body?

I look forward to your answers. I would be more explanatory but typing is difficult for me (recent surgery).

Good luck

The press comes with TWO (2) adapters for priming, one for small primers and one for large primers. I often forget to change it when changing calibers.

It sounds like you are using the large primer adapter for small pistol primers.
Please check, they are different size cups in them. Also check that there is not an excess of lube that has gotten into the cups.

Lee Turret Priming

Sid,

Try this: With the shell holder in place and an empty priming arm -

1) Push the priming arm in and lower the ram until the top of the priming arm goes completely thru the shell holder. You should feel no resistance when the priming arm goes thru the shell holder.

Let me try to furnish a bit more detail. The cup in the primer arm is not moving down against the spring so that the base of the cup will move up and force the primer into the opening in the bottom of the cartridge case. Everything else is working fine.

The problem is solved. I'm not sure what I did but it is all working fine now.

That works for me. I love it when things remain a mystery.

Did you mean perhaps that the ram for some reason is not seating the primer in the pocket?
So glad it fixed itself.

My guess would be a grain of powder, or a small chip of metal had it jammed

I think Snyper is right. I believe a small chip of metal was blocking it. Everything became okay after a thorough cleaning of the parts involved.
