Something I didn't know until I spotted some threads dealing with it on this forum: Brass that's been through a hot enough fire is no good for re-loading. Now, it's pretty obvious that some fires would certainly be hot enough to cause damage ("hey, it melted to slag -- can I reload it?"), but here's my problem: some brass that I've collected before knowing about this I pulled from trash bins (large steel drums) at a range (really -- not recylcling bins, just trash), and I know that there were fires made in some of the bins. However, from what I've ever seen of the trash cans there pre-fire, and from the amount of ash contained, I know that these fires were small and short lived. However, it worries me just a bit -- I'd sure hate to toss out hundreds of scavenged rounds unless the worry was very well justified! (I've pulled perhaps 50, perhaps as many as hundred, rounds from the trash bins -- but they're mixed in with other cases found on the same days, and I can't distinguish them visibly -- if I had been able to, I would not have collected 'em.)
So:
a1) what's the worst thing that could happen if I reload and fire a cartridge that's been fire-damaged? (And explain your work -- that is, don't just say "You'll experience a kaboom, and God will strike you dead" without explaining the reasoning.
a2) How much fire is too much for brass to remain viable? I know that the answer "any is too much" is convenient, but it also seems like a cop-out. I'd like to know a more detailed idea; if a case is in a barrel where a fire was lit which lasted less than a minute and burned only paper, what are the odds that it's affected? I understand that the military runs brass through something like a giant furnace (a popper? As in "to pop those primers like popcorn"?), which I presume runs hotter and longer than a quickie trash-shrinking fire. The popped brass is no good for reloading, I gather from reading on this site, but at what point (temperature and time) does it actually become a problem?
b1) Is there a way to tell (now that at least within certain batches of empty brass, which I know came from the range on a certain day) whether a case has been fire damaged? I tried to toss away (or rather put in my recycling collection for eventual sale as scrap) any that *looked* in any way affected by the heat, or that I found in ashes rather than in relatively pristine looking boxes which were themselves unaffected by fire (I love how neat many shooters are in their disposal ). Those, I know got added to the trash after the fire was over and done.
b2) Will a fire-damaged case seem any different on the reloading press? Will it not resize correctly, for instance?
I want to be safe, but I also don't want to be wasteful -- Insight appreciated!

EDIT: I tossed (into my recycle-for-money bin) all the brass that might have contained any of the cases that had been in the fire barrels. Seems a pity, but I was blessed at the range with a few hundred fresh, just-fired brass cases in .45, 9mm and a few other calibers.
