wonder how many people have not figured out that the rifle is at the gunsmith right now?
hopefully, he will find something easy to fix it!
You maybe should take it to a gunsmith.
Kidding. While waiting,
how do I open pages like on post 196?
I've tried right, left, and upside-down clicks.

He did not post a link, it's just a photo showing the DIY modified case. You'd have to search it on your own for the actual process.
Thank you.

Make Your Own Chamber Length Gauge from a Fired Case « Daily Bulletin
Here is a clever DIY tool we learned about from Frank Shuster, a Forum member, who, sadly, passed away in 2015. Frank was a very knowledgeable shooter who was always willing to help others. Here is one of Frank's smart inventions. He devised a way to measure the length of a rifle's chamber using...

I like the Sinclair chamber-length gauges

Interesting. Posts 195 through 197 seem to be missing.

As posted earlier by @1911nut, the absolute best way to determine your chamber length is with the Sinclair chamber length plugs. The one thing you need to know is the chamber neck diameter if it's a non-standard chamber. If that dimension isn't known, you can use a fired case neck as a guide. If the diameter of the 'collar' on the end of the plug is too large, it's easy to chuck it in a drill and use a small file to reduce the diameter of the collar. That way, the plugs work on standard and tight neck chambers.
You just trim a case neck about .100-ish, put the plug in and close the bolt. Measure the OAL of the case to the end of the plug. 5 minutes total and you know the chamber length. No guessing.
If you have the reamer, you can run that into a piece of barrel stub or aluminum for a case length gauge where you can see the neck area. Unless a reamer is specified so, virtually all reamers will have a 45 degree angle from the end of the neck to the throat...you can see this area in the pictures below. That's the area can can give you trouble with a too-long case. The neck can get pinched into this area and you can't feel it closing the bolt. The bullet doesn't release cleanly, pressures can jump around, it will spit shots on target, etc, etc.
This is all just basic trouble shooting 101. If you don't know...verify it.
For a case to work with the Hornady tool, all that's needed is an 'L' (.190) drill and a 5/16-36 tap. I stick the case in a Wilson case holder and put it in the little 7X14 mini lathe, drill the hole and tap it. Probably 10 minutes including clean up.
As to a bore scope, if you remove the sleeve holding the angled mirror on the standard Hawkeye bore scope, they measure right at .165.
If you put a white cotton patch ahead of it, you can see inside a .172 pretty well. 
2 cents worth over my second cuppa' Sulawesi.....
