Howdy all.

I've just got my brand new press set up and have loaded appx 150 shells. It works well, but I am having the primer jump issue. I've got some of the Curly recommended special grease OTW, and will address the DRY collet as shipped from the factory.

My question regards the collet position relative to the floor? of the press. It protrudes appx 1/16" above it. I noticed that Curly recommends a dremel to relieve a little of the collet material.

Should I just loosen the nut below, and set the collet fingers a touch lower? I feel like they are impacting the primer on the upstroke.

Thanks in advance,
Matt

Hold off on grinding for now. What 9000 do you have? Is it bolted down rock solid?

The top of the collet fingers have to be flush to the top of the base.(floor) Loosen the nut on the bottom of the collet and drop it down. After doing this your lifter will most likely have to be dropped down too.

There is only one 9000 as far as the collet is concerned. The 9000G and the 9000GN only have 1 major difference, the GN came with the 200 count primer feeder installed from MEC.

All true but a collet issue isn't the only thing that will cause a 'primer hop'.
Mechanize vs. Manual operation of the press can be a difference as well as the anchoring of the press.
A brand new press...hmmm.....made on a Monday perhaps.

Then take the time to help the OP and tell him what else might cause a primer hop based on the info he gave us.

What is a "primer hop"?

As I get more experience with reloading, I keep my eyes squarely focused on the primer drop since it is the cause of a lot of issues when it fails.

What does the primer have to do with the collet?

I know on my device, I start a little slowly on the down stroke to make sure I'm not jammed up on station 1 or station 3, then I push the lever firmly down until it bottoms out. That bottoming out is like a little nudge to the primer tray that is sometimes helpful to make sure it drops.

On the upstroke, if the primer is sitting a little crooked, something knocks it straight. I assume that is the collet re-opening that does that. I've come to count on that.

Something that has caused the dreaded "jump" or "hop" on my machine is having some shot wedged under the edge of the return bracket. Also be sure that the inside of the collet closure assembly is well lubed.

When your collet gets dry from lack of grease it can snap open so harshly it will cause the primer to hop out of the hole in the carrier plate. Sometimes flipping over completely and landing in the primer cup hole up side down.

One thing, when you drop the collet to make it flush with the base you have to readjust the collet. Dropping the collet 1/16" will make it size a lot smaller, possibly to the point of stressing the collet and ruining it. You will have to back off the collet closer.

You MUST read the instructions if you have never done this before. Lots of things that have to be done before you make this adjustment.

Curly probably has a thread about adjusting the collet.

You got me there.....I do not have enough information to help the OP.

If you do decide to remove/adjust the collet, and not just adjust and lube the collet closer, do yourself a big favor and get one of these before you start...

https://www.ebay.com/itm/MEC-COLLET-REM ... XQbBVRCrrH

It's a simple looking tool but it makes the job waaaaaaay easier!

Oh, and a quality 13/16" socket...same size as a large spark plug socket but MEC puts that little nut on with about a gazillion ft/lbs of torque!

Page 25 of the manual describes the process. My plan is to lower the collet and shell lifter to flush using a straight edge. Then back off the closer nut to reduce crimp. Grease the collect with the special sauce, too. Hopefully on the right track.

I couldn't find a thread about adjusting the collet. Curlys collet lube thread is excellent, though.

I found a Mec YouTube video detailing collet removal. They don't use the tool, but a screwdriver from below. I don't think I'll need to remove the collet. I'm just going to lower it a tiny bit.

The tool does look useful, though.

If a tiny bit is the right amount then that is good, but you want to lower the collet until the top of the collet is on the same plane as the surface of the loader where the hulls sit. Any higher, is too high, any lower may cause the hull to catch on the frame as it leaves the resizer.
After lowering the collet, you MUST adjust the collet closer to get a proper sized hull. You want one that is about 0.005" larger than a factory hull for maximum collet life and shell function.

Curly, I'm curious why you chose to grind your collet instead of lowering it slightly?

mdlott,

It is a small relief grind only to the side of the collet segments directly adjacent to the primer drop. The top of the collet is set level with the platform. No grinding to the top of the collet.

That small area also acts as an index reference point when disassembling for collet maintenance.

Not mandatory, but it sure is a good idea.
