Headspace
Now here is a topic I'll bet has been beaten to death over the years.
I watched a You Tube video explaining head space. The video was well done and used a cut away bolt action rifle with (probably inert or maybe its ert, who knows) what looks like a 30-06 cartridge. I am not an expert at the subject but I now understand what it is but what is confusing me is what it's called.
Why is it called headspace?
