I got a Hot Deal (tm) the other day: nearly 200# of mostly .38 Special brass. It looks pretty good at first glance, some is deprimed and a fair number is actually primed but not shot. Wondering if the primers were any good, I stuck 4 in a revolver and fired them. The first 2 went "Bang!" just as they should have, but the cylinder was kinda stuck. Pushed it open and found both primers backed out a bit. Removed those 2 cartridges and fired the other 2. Those primers didn't back out. No powder was involved, of course.
I'm figuring on cleaning the stuff, packaging, then selling it, as I load only .357 brass, even for light loads.
FWIW: that much brass is 4, 5-gallon buckets, each about 3/4 full. It's a LOT of .38 Special brass!
