So I’m getting into reloading .223 and have about 1000 pieces of brass sized. I’ve divided the brass into three bins, Need Trimming, Too Short, and No Trim. The manuals all say trim to 1.75 with max length 1.76.

I’m using a Hornady digital calipers there I use to measure completed pistol brass. But if I move the brass a hair either right or left, the measurement changes. So 1.748 can become 1.744.

So I’m going to use the Frankford Arsenal Case Prep Center to prepare my brass. I’d like to set the trim length to 1.748 or so. But the changing numbers are making that difficult. I plan to use a case that is exactly 1.748 to set the trimmer and go from there. So the ones that are too long won’t be a problem, but what of the ones that are measuring less than that? Do I toss them?

I also got the military crimp remover to add to the station.

Am I worrying too much? Is .003 of an inch an issue? I don’t want to have any problems.

Thank for all the advice in advance!
