All these tools are comparators. Comparing one case to another. If you have a "zero" headspace gauge, you can then compare it to your case size.

Easiest is dtil to take the rifle to a gunsmith and ask him to measure the headspace.]]> General Discussion janfred https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4443 Re: Old question: milsurp in a hunting rifle? https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4440 Thu, 16 May 2024 11:45:59 +0000
A cheap trick to get similar results is to use a sized 9mmP case.  Stick it over the 308 case mouth and measure from 308 base to 9mm base.  The exact measurement on a fired case, a new case and a "bumped" case will usually tell you the story.]]> General Discussion 223 https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4440 Re: Old question: milsurp in a hunting rifle? https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4429 Mon, 13 May 2024 12:47:45 +0000 General Discussion Treeman https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4429 Re: Old question: milsurp in a hunting rifle? https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4428 Mon, 13 May 2024 12:45:40 +0000 https://safarioutdoor.co.za/catalogsearch/result/?q=Chamber+Length+Gauges

Cleverrrrrrrrrrrr !

Its is so to say a way of finding out if you need to or not have measurements done professionally.

Purchase the right gauges and measuring instruments and learn how to use them
No need for "professionals"

Any idea what this would cost for 8-9 calibers, just as a once of use, to get a once off answer, even for just an answer on this one rifle once off ?]]> General Discussion Treeman https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4427 Re: Old question: milsurp in a hunting rifle? https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4425 Mon, 13 May 2024 08:49:56 +0000
Size 5 cases to minimum, trim to minimum spec, load a moderate charge and shoot them in a clean chamber. Now compare case length before and after firing.]]> General Discussion janfred https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4425 Re: Old question: milsurp in a hunting rifle? https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4424 Mon, 13 May 2024 05:25:33 +0000 General Discussion Ds J https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4424 Re: Old question: milsurp in a hunting rifle? https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4423 Mon, 13 May 2024 05:01:31 +0000 General Discussion oafpatroll https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4423 Re: Old question: milsurp in a hunting rifle? https://systemz.online/general-discussion/old-question-milsurp-in-a-hunting-rifle/paged/2/#post-4422 Mon, 13 May 2024 04:24:03 +0000 SAAMI chamber print can be found here

If I use the GSC method I should be able to get a case sized to the actual specs of my chamber. Then, if I were to compare that to SAAMI specs, I should be able to calculate the difference in my own chamber.

A case sized - and or fired in your rifle chamber will always be slightly smaller than the actual chamber
It needs to spring back enough to be able to be extracted.
The ONLY real way to know what is going on in your rifle chamber is to cast it using cerrosafe or similar low melting point alloy

Unfortunately no-one has been able to tell me where to get this in SA ?
