I load and shoot it all, I store it in big buckets and sort out the nickle and the berdan & other junk.
Speer/CCI/Blazer (All the same, made by Federal/ATK) brass is all good stuff as far as I have seen, it is well made and I would say it is as good as anything else out there.
PMC and Aguila load just fine for me- PMC is Korean and Aguila is Mexican- what I've seen is in spec and no problems.
NNY is Prvi Partisan, imported, and again, I have had no trouble with it.
I've had more "problems" with .mil brass with crimped in primers (in 9mm, really!) those get dumped in a cup for when I have enough to bother setting up the small swager and fixing them.
A-Merc brass is the bottom of the bucket but I shoot that for the places I have to leave brass behind. Out of round, soft, primer holes are off center, flash holes out of position, etc.
So far I have had only minor trouble with Seller & Belloit in that the primer pockets are tight, and they make a range safe ammo that is steel cased washed with brass- looks just like brass, right down to the red primer sealer. Need a magnet to sort it out.
