I shoot a lot at a particular indoor range and in addition to reclaiming my own brass I may pick up "a little extra". The bucket represents about a year's worth.
There have been discussions in the past concerning 45 acp and small primers and every time I sort my brass I find more and more SP 45. (This is old news and a lot of reloaders have been cursing under their breath and tossing the SP 45 cases.) But this time round I found an interesting fact:

I sorted and cleaned all of the LP/SP 45 acp last night into three piles:
(1) Blazer is all SP (and is in no way "Green" or "Lead Free")
(2) Federal is a mixed bag
(3) Everything else is LP

Then the Federal was further sorted by SP/LP.

I had about 1000 rounds total (I'll know exactly how many by the end of day today when they're all loaded) and for the first time
THERE WAS MORE SMALL PRIMER BRASS THAN LARGE PRIMER.

Not a problem, per se. I load it same-same and it shoots same-same. If I miss one in the press it is no more of a disaster than finding a .380 when loading 9mm - just remove the offending case and get on down the road.

I guess I'm posting this so some of you may rethink your "toss-it-and-forget-it" position because there's a train a'coming and we can't stop it.
