...just remember, these gauges are reamed to SAAMI "min spec", your specific chamber may vary. With all of my calibers that I have these gauges for, before any initial loading during development I use them to check my sized case dimensions, if they fit well I know I most likely won't have an issue with chambering (AR's). I also check if my initial bullet seating depth for a particular bullet will fit without being too long. After the 1st firing of cartridges set with what the gauge told me, I will remeasure the fired case to determine what my chamber tells me so if necessary, I can adjust my dies accordingly (which is usually the amount of shoulder bump and how it affects the headspacing).
