Incipient Case Head Separation

[fguffey]

Every reloader should know exactly how much your Full Length Sizing Die is pushing back the shoulder. With the NEW Case Gage Depth Micrometer you can do just that! It has never been easier to measure you cases headspace before and after sizing. The Depth Mic allows you to slip the micrometer perfectly over the top of the gage with your case inserted into the gage and take a measurement. Graduations of .001 comes with a Gage Block. One size works for all L.E. Wilson Gages.

Just an opinion but that looks to me like a reloader wrote that; a case does not have head space and reloaders should have been able to determine the length of the chamber with the Wilson case gage ever since 1954 if they measured before firing and again after firing and again after sizing. One thing I do find interesting is the part about:

Graduations of .001 comes with a Gage Block

I am the fan of transfers and standards meaning gage blocks are standards.

And no one has said anything about the use of the word gage. My Machineries' hand book from about 1912 plus or minus 4 years used the word gage and has been consistent with the word gage ever since. Same with all of my Starrett data books and catalogs going back to 1920.

I built this device in order to get actual measurements of the case wall from the inside.





That said when everything is setup right, separation of the case head is a non issue.

L.E. Wilson Gages.

That is uber cool. Of course we can do the same thing with tools we should have laying around, but that is sweet. Sort of like the RCBS Precision Mic. Kind of. But for tool geeks, it's neat.

Yep.

I bought one of these and really like it. After playing with it and the Hornady Headspace comparator, think I am finally getting it in my head about shoulder setback and so forth.

Thanks Walkalong, this post helps to make it easier for me to know what to look for when I run my bent paper clip inside my rifle cases. Very educational!
