Priming cases is one of the most important steps in the ammunition reloading process. It can also be the most frustrating! If you want to optimize your reloading workflow, it’s imperative that you have a priming setup that’s easy to use and performs up to your expectations. In this post, I’m going to show LEE’s updated “Auto Prime” hand priming tool (LEE #90230). It shares some similarities with the LEE Auto Bench Prime, and even uses the same style of shellholders.
In this video you saw the “very first” cases I primed with this tool, and so far it’s performed 100%. Furthermore, it was super-simple to setup. I’m sure part of this had to do with the fact that I’m already accustomed to the LEE Auto Bench Prime which is very similar when it comes to setup and operation. What’s amazing about this tool is that you can get the New Auto Prime *and* a set of 11 shellholders for less than $40 street price. That’s pretty amazing!
You may be wondering what’s changed in this “new and improved” version of LEE’s Auto Prime. Here’s a short summary of the changes:
- New ergonomic profile with finger grooves
- New folding primer tray (same as LEE Auto Bench Prime)
- Primer isolation feature makes this new tool safer to use (reduces likelihood of mass detonation by separating primer being primed from rest of primers)
Here’s what comes with the New LEE Auto Prime tool:
In this picture we have: (clockwise from left)
- Large primer insert
- Instruction sheet
- New Auto Prime tool body with small priming insert installed
- New LEE folding primer tray
It is important to note that this tool does not work with “Standard” shellholders that turret or single stage presses use. The shellholders used by the Auto Prime, New Auto Prime, and Auto Bench Prime are optimized for use in these tools, and are quite affordable. I would suggest the set of 11 shown in this picture:
Here’s the list of cartridges that can be primed with the New Auto Prime:
As you can see, with this affordable set of shellholders (I saw a set for less than $16. online) you can prime a WIDE variety of cases- this set includes shellholders 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, and 19. Additional shellholders shown in the table above can be purchased individually.
I’m just getting started with this tool- look for it in upcoming stories and videos!
