Fell into a large quantity of 'defective' 9mm ammunition and am breaking it all down into components at the rate of about 250rd / hour. Things got a good bit faster and easier once I figured out the proper adjustment on the collet puller die and then made a wood handle for the 1/4" steel dowel it came with, which was beating my hands up pretty good.
I'm keeping half in exchange for my labor. Not a bad deal for me, I've got more time than money, lately.
I first did a rough count by volume (~6800 rounds), then did a sort; empty brass, odd calibers, .380, loaded rounds with plated LRN and proper primers, loaded rounds with plated LRN with missing or flipped primers. And rounds loaded with golden saber JHP bullets. Then I set about processing it all. Breaking it down, resizing the brass, punching the improper primers, disposing of the unknown and mixed powders as garden fertilizer. Still have about ~2300 rounds to go. Once it's all broken down and parceled out, I'll get busy turning my half back into good ammo.
