"As matter of semantics for a technical activity in which the correct use of words matter; there is no such thing as a GO-NO GO gage for cases, those are made for chambers and are illustrated in post #7"

Reading and comprehension:

"A narrow, straight instrument, like a steel scale, will be of assistance in checking cone-to-head length"

Wilson calls the straight edge "a narrow, straight instrument, like a steel scale", to avoid the appearance of showing off, I refer to it as a straight edge, any straight edge and the set up table is one big flat straight edge, to take all the guesstimates like fingernails etc., I suggest using a feeler gage AND! a straight edge.

Again, for those of you that have a go-gage and the Wilson case gage the accuracy of the gage can be determined with a standard (think!) if both gages agree, both are standards.

"cone-to-head length" they did not say DATUM, they did not say SHOULDER, they said CONE, both Wilson and myself understand the CONE, "correct use of words matter" Reading and comprehension makes that possible.

There are those that can only use the gage as a "drop in gage" then there are those that read and understand "what it is they read", then there the few that see the chamber after the bolt closes and all the light is shut out. The standard, the transfer, the feeler gage is the most versatile tool I have, for some it could be too complex, to others it could be too archaic, Me? I can not see over my tools because the wall is 3' foot away.

The dial caliper: Think of it as a combination feeler gage/straight edge depth micrometer/debth micrometer, or use the Wilson case gage as a drop in gage.
