I store sized and lubed bullets in plastic or foam ammunition box trays. This prevents the bases from getting damaged and the bullets don't bounce against each other so that soft lubes stay intact. I wrap the bullet trays in butcher paper to keep them from attracting dust, and stack them in metal ammo cans for storage. About 1000 .44 or .45 bullets fit into an M2A1 cal. .50 ammunition can and stored in this manner blackpowder lubes remain good for years and don't dry out.
