It all depends where you want to spend your time. Chasing brass at a match really distracts me and takes away from the enjoyment, which is why I'm moving to exclusively 9 major over 38 super; the idea of marking and retrieving my 9mm brass makes me dizzy. I also don't sort headstamps or roll size, I scoop up piles of random brass at an indoor range, tumble, load, tumble. I then gauge each round in my barrel before it goes into the plastic box I take to the match. I hold the barrel pointing up, slip the rount into the chamber and if it drops out free, it goes in the box, if not I flick it out into a bucket to be used in practice. Then I scan the headstamps to check primers and relegate stepped cases to the practice bucket.
I then have match ammo which has already been in the chamber of my pistol. The practice ammo generally works fine too, but the match ammo works flawlessly.
