 How to use a Dillon Case Gage

I ordered some Dillon Case Gages in .223, 9mm, and .45 ACP. They didn't come with instructions.

How the heck do I use these things? I understand you put a cartridge in them. I'm not that dense.

For example, the .223 gage (the only one I opened so far) has two ridges or cutouts on it, on by the neck/mouth, the other by the head/base. What are they for? I'm going to guess the ridge by the mouth is for max/min case length while the one by the case head is for max/min headspace. Well?

I purchased the gages because I had some issues with some .223 that I over-crimped and crushed/bulged the shoulder. They jammed up my Stag-15 very tightly. I have since found the cause of the bulging and fixed it.

Thanks in advance, gents!
