Wow, maybe I'm just lucky. I started scrounging Friday, July 13 2007 and since then I've picked up 5-gallons of 9mm, 3 gallons of 30-06, 2 gallons each of .223, .45 and .40s&w. plus half-gallons each of 7.62x39, .380, .357, .44, .38sp, .30-.30, .308, .30-M1, .357sig, FN 5-7, and misc oddball calibers. Plus 5-gallons of scrap brass.
I gave my FIL a cool-whip container full of LC-'07 HS .223 and it honestly didn't seem to drop the level in the bucket any.
My wife's actually getting annoyed at how the brass containers are spilling out from the workshop into the den.
I save stuff I don't even have guns for 'cuz you never know.
