For pistol, I just shoot until I see signs of splitting. Most pistol calibers last a long, long time, especially if your not loading real hot loads. I've been reloading for about 15 years now, and this method has worked well, and much less cumbersome than trying to track number of times fired for each case...! IMO, tracking exact number of times fired makes sense for rifle rounds, but not with pistol. And no, I find no need to clean primer pockets for pistol cases, unless you're bored!
That said, in an effort to not load one case more times than another, I keep two pails/containers for each caliper, an 'A' and a 'B' container. The 'A' container is the starting point, and the 'B' container holds the brass that is subsequently fired from the 'A' container. Once all the 'A's have been loaded and fired, those casings from the 'B' container are then cleaned and put back into the empty 'A' container and the cycle is started again. Probably sounds confusing, but it works for me, and again is done in an attempt to keep the rounds-fired count even among the casings.
I use Sharpies to mark the case heads when I'm testing different powders and/or loads. If I'm testing accuracy among three different loads using the same powder by increments of say .01, I will mark the lowest ones with a blue Sharpie, the mid with green, and the highest with red. Even when separated in different ammo boxes, the Sharpie helps to keep things organized when I'm at the range, and when I'm inspecting cases for pressure signs. I'll do the same when testing different powders in the same caliber.
Hope this helps.
