I don't disagree with you in any way, I just choose to not reload the brass from my open gun. Despite my name in this forum, I shoot a ck arms open gun. A nice well built 2011, and all I can afford as a school teacher. I did start with a glock, but no longer shoot major loads through it. I shot at a range, where, the match director sells brass from there indoor range. 20 bucks per 1000. I buy it, separate it by head stamp and load one head stamp at a time. I have had the step, on some brass that has came out of my 2011 open gun, which is, at a power factor of 173. CK arms, say you need a power factor of 172 for the comp to work properly. They also say to not pus the of over 175. I case gauge every round before it goes to a match. This is what works for me.
