The link you have to the RCBS precision mic is the correct tool for measuring headspace. To use this simply take a case that has been fired in your rifle and measure it in the mic. Then subtract .002/.003 from the measurement to use when adjusting your sizing die. This measurement will be the measurement you will use for your rifle and brass to have the correct headspace. All you do is size your fired case in your sizing die measure it with the mic and adjust your die as needed.

I have a case gauge but I never use it.

I don’t use a chamber length gauge for a semi-auto. Just use the trim and MAX case length listed in your loading manual.

I have a bullet comparator and it is nice when seating longer than mag length, but if you feed from your mag it is not needed.

The only time I crimp for 223 is when there is a crimp groove on the bullet. Most (if not all) target bullets don’t have a crimp groove.
