Primer Depth Measuring Tools

[PeaShooter]

I was looking into getting some kind of a tool to measure my primer depths. I use a 21st Century primer seating tool that does one primer at a time and I have to change the holder each time I change from PPC to BR (and others). I usually check the depth on glass to make sure the primer is not sticking out but I need something better. I feel that the Accuracy One measuring tool @ $100 would work. I then started googling this and found the one at Primal Rights and thought it looked nice. In a world of over priced stuff for shooting this item surprised even me. I am used to everything Benchrest being double what you think it should cost but this is at a whole new level of absurdity. Anyone know of any other tool that can tell me the depth of the primers?

Check out the F-Class Products, it works good and will do all cases without having to buy case specific parts, you just adjust the indicator, it only takes a second to adjust

Every bench rest shooter I know seats the primer until it bottoms out then gives it a little more squeeze.

I’m with @Andy Work on this subject but …Accuracy One does make good tools for those that want to gage primers.

Precision Primer Gauge

The Precision Primer Gauge takes precision measurements of primer pocket depth and the depth of seated primers in relationship to the face of the case head.

Holland make a good tool too. It's quick and easy to use. I use a Derraco to seat primers, but I use the Holland gauge to verify the depth.

This tool has worked out pretty well for me. It takes about 15 minutes to figure everything out, and after that, it's very easy to work with. You should probably uniform your primer pockets to make sure you are seating the primers all the same depth.

First you'll need to make sure your primer pockets are all the same depth.
Otherwise, just measuring the depth off of the base or just seating by feel
will be off.

I use a primer pocket uniformer every time to ensure the pockets are all the same depth, then use my Mitutoyo digital caliber depth gage to verify all primers are .002" below flush.

Seems to have been working ok for many years, but am I missing something by not using a dedicated tool for this?

I use and like the Accuracy One tool, as can not only measure seating depth, but also primer pocket depth. I've got to know both so I better know the relationship between the two points of contact.

If you want a very inexpensive tool to measure seating depth, how about this one on Amazon???:

The RHP tool does everything the Accuracy One tool does, and more.

The primer should be seated firmly to bottom of the primer pocket. The depth is immaterial. This is easily accomplished by feel using any decent hand held priming tool.

Andy Work, tmwinds you are beating a dead horse, this nonsense is not going to stop anytime soon.

Is there any evidence for setting primer depth? Please point me to it. I have just ordered the new Lyman bench primer, which can set depth, so I'm interested to see how this translates to targets - and I'm too lazy and cheap to do the work myself.

he does lots of depth and weight tests

There's a range between crushing too much and seating to high that works just fine, like mentioned in the conclusion in this YouTube video I think you should find interesting.

I like to measure the primer pockets (preferably having them uniformed) and measuring the height of the primer as there can be a significant difference where the primer is seated too deep leading to an ignition problem (like with a light primer strike or a misfire).

Thanks for the link. Very interesting.

I seat the primer until it bottoms and never measure anything. I do make sure nothings sitting proud.

When you cant shoot consistently any better over time, then buy a primer depth tool. Or not. lol
