"WHY" would you use a new cartridge case of unknown length to check head space.
A new cartridge will be of fairly standard length or a length that will fit into the standard chamber of a standard weapon. What good is purchasing a cartridge if it does not fit into the weapon it was designed to fit. It is does not fit my newly head spaced weapon it is either 1 of 2 problems ;
The cartridge is too long - maybe
or
My Headspace is too tight - more likely
Why would you use another rifle of unknown head space to judge the rifle you are working on.
If a new round chambered, cycled, and behaved nicely in a brand new, ie, just received my rebate check from Remington last week, then its highly likely that the head space is pretty good, or good enough to pass Remington's internal QA controls, in addition, it did not blow up on me when I shot it. In my limited opinion, this is a pretty good reference.
Also if you were just installing the barrel "where" did the fired brass come from???
I pick up my own brass. I clean and size my own brass. I can tell you when and how many times the brass was shot and what was the load for each of my Tupperware containers that I have my brass in. The fired brass was from the Savage 110 with the older barrel and the new Remington. The Savage fired brass was longer than the Remington.
The new brass is brand spanking new from Lapua.
My reason for adding to this thread was my impression that even when I did it correctly, by the book using the GO/NoGO gauge, the head space appeared to be too tight. Using additional "Tool" at my disposal, Used Brass, New Brass, New Rifle, and also the GO/NoGO gauges, I think I got the fit correct. You may disagree, and I do appreciate any feedback.
