After using several tools over the years for seating primers, the Lee bench prime became my go-to tool of choice. That is, until the point I fell down the rabbit hole. (That subject is for another time.) Today’s installment in the how-to series will be on how to use the Lee bench prime in 6 easy steps.

As I mentioned, I’ve used many tools to insert primers into brass cases. The Lee was my favorite due to its ease of use; a teenage drop-out, high as balls, could operate this unit effectively.

Let’s begin, shall we?

Step one

Due to this unit’s small footprint, I recommend mounting it to something solid. You could easily bolt it to your bench or whatever works best for you. In my case, I used an in-line fabrication mounting plate.

Step two

Now, insert the correct-size primer feeder into the Lee bench prime. Reading the size markings on the side of the unit can take time and effort. It pays to double-check.

Step three

Now that the correct-size feeder is installed insert the shell holder into the tool. It would be best if you had the proper-caliber shell holder. Refrain from assuming you have the correct one. It is effortless to look it up online. I’ve made the mistake of not doing so.

Also, you have to use the company’s holder. These have a large-diameter hole in the center, allowing the primer plunger room to move in and out. Other companies’ offerings will not work with this tool.

Slightly slide the primer feeder backward and insert the shell holder. Then release the feeder, and you are almost ready.

Step four
This is where the fun ends.

Now it is time to load the primer tray. Unfortunately, the tray is made of plastic and operates as such. Many others, myself included, would happily pay for an upgraded version of that part.

This tray has a switch with three different settings. The settings are locked, open, or on. Due to the material, it operates roughly. I have lost count of how many times I accidentally switched to the open setting instead of the on setting and spilled primers all over my bench.

Lock: The tray is closed and locked in place.
Open: The tray is open for loading, holding, and spilling primers.
On: The tray can feed primers into the unit.

There isn’t a one-size-fits-all way to adequately describe how to load the tray. You have to mess around until you figure it out.

After loading the tray, slide the switch to the “lock” position.
Next, insert the tray into the feeder.
Last, carefully slide the switch on.

Step five

I like to operate the handle a couple of times. Make sure everything is feeding correctly. Sometimes, you have to tap the tray to get everything in motion.

Step six
Now, it is time to get down to business.

Insert your brass case into the shell holder and lower the handle until it stops.

You have just seated the primer. Rinse and repeat.

Always wear safety glasses when using this piece of equipment. Also, do not apply pressure when the primer is seated. If you do, you will likely get an early 4th of July show. The unit is not designed to crush primers. That tool is for a later article.

Before anyone asks, I am not receiving any compensation for writing this article—unless you consider making my reader’s life easier as compensation. I hope this article on how to use a Lee bench prime in 6 easy steps has helped you in your journey.
