As I use range brass and I am not reloading pistol for 50yd match bullseye accuracy (I am an action pistol IDPA/USPSA shooter), I do not bother with a lot of headstamp sorting and other pre-loading inspection time. My g/f and I both shoot, and I do all the reloading, so she gets to do the quality control step. Since I switched over to Lee full-length resizing dies, I don't think I have ever had a case fail to gauge properly, but going through the motions gets a second set of eyes on all the cases to find any dings or cracks I might have missed during the actual reloading, and just a chance to see that everything came out all right.
By the way, the small primer stuff is easily picked out during reloading when the primer won't seat, and the A-Merc brass is even easier to find---it adheres to the powder funnel like nobody's business! (First time I ran across A-Merc resulted in my disassembling the powder die and taking a hacksaw to the stuck case. Next time it'll be a Dremel. )
