So the argument becomes that a cartridge does not have a headspace dimension. Using the .308 Winchester cartridge as just an example and referring to the actual SAAMI drawings here is what we get:
This is not to challenge you directly Ron . You just opened up the opportunity for me to say what I've been saying on many other forums .
Actually it does because we the community over the years have chose to say it does and use the term quite often . That's how language works , why do you think English is so fun to learn . The group as a whole except or shuns an idea . We as a whole have chosen to except case head space rather cartridge head space because the cartridge includes the case , primer , powder and bullet . To measure case head space you only need one of those things , the case .
I could go into great detail as to how terms and or words evolve over time . The best example right now is Hack/s . Somewhere in the last 10 years or so it has become a term to mean a good thing , way to best achieve something quickly etc . In my day it also meant many things but they were always bad . Like he did a hack job or you're a hack . 30yrs ago hack/s never meant how good , smart and innovative you were . I'm coming around to that one but it still bothers me but as you said
Personally rather than swim against the currents or fly into a headwind
is how I think about it as well . That doesn't mean I have to like it
