I can tell you what NOT to do: don't do what I do. I have ziploc baggies of brass in boxes in a storeroom attached to the house. Also have brass in unmarked boxes, snack jugs, carboard mailing boxes, used ammo boxes, new ammo boxes, 30/50cal ammo cans, oyster buckets, and every once in a while I'll find loose, mixed brass in sandwich baggies in an old range bag. It's like a never-ending Easter egg hunt of miscellaneous shooting items. I found a plastic shopping bag from a pawn shop I used to haunt decades ago with four sleeves of Winchester LPP in it. It was wadded up in an old NRA range bag I used before Y2K. The price tags said 5/$20 - $4/each - and there were only 4 in it so... Not sure how much I paid, if anything (Rich used to just wave his hand and say, "I'll get you next time..." when I picked up sale stuff) or when I got them. Some day I'm going to go nuts and all of these little surprises will be like Christmas every day.
