What is 'headspace'?

Headspace is something I struggled to understand at first, especially, when I load all sorts of cartridges, but when reading about it, everyone seems to discuss one specific type, missing the others.

This is mostly a reference for me, but I thought a lot of people will find this very useful.



This appears to be a rimmed cartridge, and it’s just a guess of course, but I would presume that headspace is determined by the rim of the case.

The video discusses all types of headspace…
