Frequently Asked Questions


When you purchase the gauge, you should receive an automated email with the receipt. And then another one when the gauge ships(almost always this is within 24 hours) . This email will include tracking info. Often, these emails are caught in junk mail filters. Please check your junk mail folder. Although we do try to respond to emails quickly, you will still get the tracking info quicker by looking in your junk mail folder. If you do not receive these emails, please feel free to contact us using the form on our contact page . Sometimes it helps to add us to your list of contacts. Thanks for your business!
Because we try to hold very tight tolerances, each new caliber requires several caliber specific tools to be made . Setup costs are not cheap. So we generally won't make a custom one off gauge. Additionally, we can not make a gauge just off of a fired piece of brass. This would be about as custom as it gets. Between the time involved in measuring the brass, then modeling it, and buying the tooling, it would be very expensive. However, we are adding new calibers as we can. And we do listen to customer feedback for which ones to make next. So if you have a caliber you are interested in, email us and let us know. We may even be working on that one already.
Other companies case gauges are only the length of the case, and often have a step on the end to indicate trim length. Our ammunition gauge and slotted ammunition gauge are the full cartridge length (COL), so they can not have a step on the end of the gauge to show trim length. On most pistol cartridges where the case headspaces directly on the mouth, the need to trim will be indicated by the headspace measurement. Our gauge will show this clearly. On rifle cartridges, where the cartridge headspaces on the shoulder or a belt(for belted magnums), there should be some space between the mouth of the case and the corresponding end of the chamber. So you can not use the gauge to check for the trim length. This can be checked with calipers.      
Our slotted gauge is patented, with the following utility patents: US9513097B1 and US9863748B2 . Manufacturers who are interested in licensing are welcome to contact us.
We do sell outside of the US. Shipping is done via standard postal mail. The website ordering for international is currently disabled, so you will need to email us directly using our contact form for sales outside of the US. We do not currently have dealers outside of the US, so all international orders should be done through us.    
The password reset mails a reset link to you. However, if your email program thinks our email is junk, they will get rid of it. If you email us and don't hear back, or don't get a password reset, it is probably because the password still needs to be reset.

The gauges are made to the minimum chamber dimensions. Most chambers will be larger than this. So it will reject some rounds that may still fit your chamber.  If you only use the gauge as a pass/fail chamber checker, any rounds it passes should fit into your chamber without an issue.

But using the gauge just as a pass/fail chamber checker is missing its use as an inspection tool. The slot makes it easier to pinpoint interference, and the 3 steps on the face are directly pulled from the headspace reference specs for both the cartridge and the chamber.

Since the dies and other parts in the reloading process are all designed around making ammunition that will fit an in spec chamber, then the question should be why wouldn't it fit the gauge?  Even if it does still fit your chamber, the fact that it is failing the gauge is telling you there is something in the loading process that needs to be looked at. It could be a problem with neck thickness or concentricity on brass formed from other calibers. It could be neck bulges from the bullet seating process. It could be that the bullet is not seated straight. It could be burs on the case mouth from cutting the case. There are a long list of other potential problems that can be found using the gauge as an inspection tool.

Some people just want it to fit the one firing chamber they test it in and aren't concerned about any quality control beyond that.

Factory ammunition not fitting the gauge is not an indicator of a defective gauge. The gauge is the reference tool, the ammunition is what you are inspecting. More likely, factory ammunition not fitting the gauge means the factory ammunition is out of spec. This could be from something that occured to it during shipping/handling, or it could be slightly out of spec/tolerance from the manufacturing.  It is also possible to have dirt/debris on the ammunition or gauge that needs to be cleaned off. Does all of that particular ammunition fail the gauge, or just some of it?  Can you identify where it is sticking in the gauge? This does occur, and usually the ammunition being out of spec is the issue. But we are happy to help you diagnose this, so send us a message so we can help you and make sure that the gauge is working properly.
