i have this odd habbit of ziplocking all my stuff. my dies get cleaned and lubed, back in their plastic box, then slipped into a ziplock. my 1# powder jugs, after use, get slipped into bags. all my brass is sorted and bagged.. primers bagged.. etc. bullets bagged.. etc..
not sure if I'm going overboard.. but figure it can't hurt.. might keep corrosion off.. or if an errant florida storm comes thru and beats in a roof/wall/window, maybee the stuff will survive better..
just about all of my loaded ammo.. commercial or milsurp is containerized as well. some of the milsurp is already tinned or in battle packs.. and the commercial stuff either gets bagged and then boxed , or is kept in sealed ammo cans with a lil sugar packet sized dessicant pack tossed in.
again.. might be overboard.. but... makes me sleep better..
