I am a cheap skate reloader. I do have a few of the fancy plastic boxes for ammo storage. Though they are all the same color. I can tell them appart by looking. All are translucent green. The top has the caliber writen on it. I do use a pharmacy label to write the load info on so I know exactly what the load is. If I have more ammo loaded than I have room in the boxes for then I have boxes for each caliber that I rescued from the brass barrell when people threw them there. (Oh wait I mean donated them to me.
) I use the same pharmacy labels to write the load info on them as well.
For my .45 acp bulk ammo I put it in plastic jars that once were 3 pound peanut butter jars. They are water tight, and hold a lot of ammo. Very heavy if you are the poor sap that has to carry it a long way too.
