New Accuracy One Precision Primer Gauge
For centerfire rounds, consistent ignition (and low ES/SD) all begins with the primer in the base of the cartridge. When the firing pin strikes the primer, it sets off a small flame/spark which lights the powder in the case. Energy from that burning powder pushes the bullet out of the cartridge, down the barrel, and out to the target. It’s fair to say, then, that accurate shooting all begins with the primer.
When seating primers, consistency counts. You want to make sure the primer is fully seated in the primer pocket in the base of the case. You want to ensure a slight bit of crush (flattening) for proper seating, and it doesn’t hurt to have very consistent primer seating depths. That’s why guys use tools to uniform their primer pockets.
Here’s a new tool that lets you measure the consistency of primer seating depths. We haven’t used this device yet, but Forum members have reported it works well — measurements are quick and repeatable. Will this tool lower your ES/SD or improve accuracy? That’s hard to say. However, it will definitely help you detect when a primer in a loaded round is seated too high or too low — that’s important. In addition, it can give you precise measurements for comparison testing with different types of primers.
Accuracy One Precision Primer Gauge
The Accuracy One Precision Primer Gauge will precisely measure primer pocket depth and the depth of seated primers in relationship to the face of the case head. The Precision Primer Gauge can also be used to measure the thickness of an unseated primer, allowing you to calculate the optimum seating depth for the particular primers and cases you are loading.

Product Tip from EdLongRange. We welcome reader submissions.Assembly Tips: Nylon screw is provided for securing the gauge body to the indicator. The contact point of the indicator must be removed to provide proper function. Also, please note that the standard gauge body is not compatible with cartridges that share the .338 Lapua case head diameter unless the diameter of the magnum step is machined to .595” to accept the larger diameter case head.

You could use it to measure pocket depth, primer height, and seated primer height/crush. This does not put the primer at a set value/crush. It just measures it.
You can do all this AND actually put a primer to desired crush -with the indicated K&M primer seater.
Maybe the folks at Accuracy One didn’t know this?
These guys need to get into the 21st century with their purchasing department, PDF orders really! Guys should just make an amazon store
Can this tool be used with 6.5 Creedmore?
I just received mine yesterday. It was worth the wait, and if you are thinking about getting one, it’s back in stock! I’ve been spoiled by Amazon’s SLA, but swindled when it comes to quality and authenticity. Trust is waning there. Oddly enough, I redesigned Amazon’s shipping platform and all their 40 other vendor tools a few years back. Accuracy One is manufacturing top tier precision tools that you can order via phone, email, or mail. They don’t have the overhead of digital fulfillment and I think that means they can put more energy into making quality products. You are dealing with real people and superior craftsmanship. When I opened the box, the guage, primer stems, and zeroing blocks gleamed in the light, showing absolute precision machining and finish. When I actually start using this, I don’t think I’ll be disappointed. It came with directions too which is rare for this hobby.
Yes this guage will work with 6.5 Creedmoor since it comes with both small and large primer stems and Creedmoor brass comes with small and large primer pockets. I believe it depends on the brass manufacturer, but you are covered with what comes in the box.
Hello,
I am looking for a device to test a small pistol primer.
The instrument can be used.
Please help,

I have used your primer gauge quite a bit since receiving it, with good results until today, when working with 338 Winchester Mag cases. Your literature states that the main body is compatible with .532 case heads. There is no step for a perfect fit for the 338 Win. Mag.base (.532) and without that, there is no precision.I will be calling you to straighten this out. Regards, W. West
I have a new Precision Primer Gauge. After a lot of use it does not work any longer. Can you fix it for me? I do not have the necessary skills to do so.
Please let me know your procedures for doing so.
