When sizing your brass with minimum headspace dimension is it for case life or accuracy . The reason I'm asking is if you bought store bought match ammo . Let's use federal match 168gr. Sierra for a example . They will chamber and fire accuratelyin almost all rifles . There case measures .003 to .004 differences measuring from bolt face to datum line In 308 and a AOL of 2.800 . Maybe powder charge is most important
Cases maybe better self centering along with the bullet , now I'm testing with .003 for the case and a .002 for a jump with the same accurate powder charge I was using before . Next Sunday will see if room makes a difference .
