Sensop:
The "micrometer" gage I mentioned used to be sold by Moe DiFina, a dealer/high power shooter from Conn, Middlefield as I recall. I have not run into him in a number of years, as I no longer shoot high power rifle competition. His "mike" measured only, and was used as I described.
Also, what you described sounds like "partial sizing", that would provice a "crush fit" when the round was chambered. This could work with bolt guns, though I wouldn't want to try it with a semi-automatic, which was the subject of the original post.
I have never seen the RCBS tool you mentioned, however Moe's case mike worked fine, I used one to set seating dies (full length) for 308 bolt rifles.
