All my .223 brass has been sorted by head stamp. The Remington brass is once fired by myself and not other peoples range brass. Almost the entire amount fell within +/- .004" of minimum trim length which is 1.750" and most of it fell under. I doubled checked what my analog calipers were telling me by using my Mitituyo digital calipers that I didn't show in the video. Also, it is very important to use a head space/case gauge. Even though the brass length measures correctly with calipers... this does not mean that the head space is correct unless you use the gauge too! I checked every piece of brass with the gauge and will random sample by chamber testing the brass with a couple of my AR's.

I usually only do random spot check's on my loads after everything has been set. When all the rounds are finished they are tested in a case gauge, and any that don't pass go into the 2nds pile.

Even then 99% of those ones function fine, but why chance it.
