I've been sorting all of my brass for a while, although I'm getting lazier about the plinking loads.

I know the OP was talking about pistol rounds, but I wanted to share this week-end's reminder about sorting rifle brass. I was working up a new load for my 7mm RM (I need lead free now that I am in CA). My brass was sorted (or so I thought). When loading the second round at book max I felt a definite crunch as the extruded powder compressed. The previous round at the same charge did not. I took another look and confirmed that the headstamp was different. I had read that the "other" headstamp brass had lower capacity. I think I just confirmed it.
