TL/DR: Once fired brass measures 1.558" base to shoulder. OK?
So, I have a new toy and not sure I understand the numbers I'm getting.
Here's what I'm working with
1. Brand new Tikka T3x Tac A1, exactly 60 rounds down the tube.
2. Brass is from Hornady Match, factory load 1x fired from this new Tikka.
3. Brass is untouched since being fired - has spent primer, is not tumbled, etc.
My Hornady Headspace comparator tells me that my headspace is 1.558". That's measured consistently across 10 cases.
1. In looking at the SAAMI specs, this 1.558" seems long? Best I can find is that 1.551" is max.
2. Am I supposed to deprime and tumble before measuring?
3. If you were me, would you resize back to minimum spec or just bump back .003" and still be over spec?
I'm not new to reloading per se, just new to actually being precise about it. Previously I just set my dies according to the manual and called it good.
