I have been relaoding pistol and revolver ammo from .380 to 44 mag. Never any bottleneck cases. Unless you count 30 carbine which has a slight taper which I belive headspaces on the mouth??. The 223 on the shoulder??
I want to start loading 223. Before I start loading for a semi auto AR15 I figured it was wise to load for by bolt action first. That way I can neck size and do not have to full length size them.
My question is on headspace. If I measure my empty fire formed brass and keep it trimmed to specified length and then keep my overall loaded length at or a little less than spec, do I need to worry or do any other measurements?
I have looked at guages such as the Wilson

But do not see what that does that I do not do with my calipers?
I have read many articles on headspace and the more I read, the more I get confused.
Perhaps to much "headspace" in the 60's
Any pointers , links, advice appreciated.
