For pistol brass as long as it is boxer primed, not steel, or aluminum. I load them, unless it has a crimped primer pocket. If so those go to the scrap brass can. I have so many that are not crimped it is not worth the effort to remove the crimps.
For rifle some get sorted by head stamp if they are for utmost accuracy. (They get more prep work done to them as well.) Others I load with a load I worked up for use in mixed brass. Difference at 100 yards with me shooting is not that different at all. Though it gives me something to do when I am bored.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
