How do you measure .22 rimfire chamber depth?

I use a headspace gauge and it is essentially like any other action. The rimfire headspaces on the rim.

With the barrel on or off?
New or Old
Ernie: Are you talking about a finished chamber or one you are about to cut? On finished chambers, I saw a smith use different length cases that were drilled so his bore scope would fit thru them. He could then see the depth of the chamber compared to the chambered spent case. On new chambers, (about to be cut) He would put a stop collar on the reamer at the point he wanted the chamber depth, then ream to the stop.

Jerry,
With the barrel off.
Fred,
I'm referring to a finished chamber.From the end of the barrel tenon to the start of the leade angle accurate to .001.
Looking at spent case length confuses me because a spent .22 rimfire case is significantly shorter than a finished chamber.
Also I'm curious as to how the smith accurately measured from the stop collar to the start of the leade angle and how he inspected
the finished chamber for length after reaming.

What I have been told
My past Gunsmith, Terry Vandeveer, told me this was how he measured and chambered my rifle. It was a Win 52D with his match chamber. Unfortunately, Terry was killed while on vacation with his grandson. His Grandson survived, but we lost Terry. That being said, I can only pass on that information as I did. Who am I to question Terry's methods. They were OK for the USAF marksmanship Team and I was quite satisfied with the results of the finished product. The results are what I look at. Look at the record in the late 90's and early 2000. I know BC " Hollywood Bill" is reading this, and I object to his reference to this thread when I am not allowed to question his methods, publicly.
