Little trick to measure your rifle's headspace is to use seating die with bullet seater removed and die cleaned. I actually use cheap secondhand seating dies for this. My 308 Win covers all the 308 family cartridges. 243, 260, 7mm-08 and 308.
It will be good to have a headspace GO gauge also to give you a baseline measurement.
In pics you can see this. A real example is my one 243 Win loaded round measures 3.492" and fired case measures 3.495" which shows I had .003 clearance for this hunting rifle.
Or you can have your gunsmith make you a gauge with scrap barrel using same reamer he built your rifle with.
