I don't worry about mixing types or brands of brass but I do give each one look after removing them from the tumbler looking for signs of impending failure or damage.

If I bought a few hundred or a thousand of one particular brand, then I will separate them from the general population to use for competition.

I have all kinds of range brass mixed together and I dont have any problems, probably be a little more acurate if you kept the brands separated.

I separated my brass just to see if any particular type was involved in my FTF's.

I've been using mixed headstamps with no problems. If I'm experimenting with a new load, weighing each charge etc., then I will pick out a number of a particular headstamp for the test. After that, I go back to mixed.

I tend to separate them after loading and use the matched brass in competition. I've never seen any personal proof that this is necessary at all, but it makes me feel better. I also have a tendency to relegate Remington .45 brass for practice only since it has less neck tension than anything else I've seen (determined by the effort needed to seat the bullet).
