Kikn The only problem with the bullberry gauge is if there is any difference between it and your chamber it won't tell you anything reliable. Custom builders will sometimes make these out of the barrel end and cut it with the very same reamer as on the barrel.

Largely true.

What I can say is that the gauge appears to be a minimum-size chamber. So, if your cartridge fits in the gauge with the base flush with the gauge, it should work in any spec chamber. It just won't be good for customizing ammunition for your chamber.

Also, if ammunition fitting in the gauge does not fit in the chamber, then you know that some trouble shooting is in order.

So, the gauge is good if you want to check handloads for several rifles, each of which has a unique but otherwise spec., chamber.

The lesson I get from this discussion is that, when ordering a custom barrel, one should automatically request a chamber gauge that gives visibility into the shoulder, neck, and throat so you can easily see where contact points are. One may still need to use marking fluid on occasion because small gaps can be hard to see.
