I have some time on my hands so, I'm learning to reload primers. Tedious, but, very exacting. There are many many formulas to make the powder. Fun to play around with the chemistry. I have even made a primer cup push-through resizer. The only issue I have is storing them safely. In a bag, plastic box or bottle they could rattle around and be dangerous or they could lose the powder inside. I saw a photo of an early primer tray made of wood where the primers sat on their sides in slots, I thought that was interesting. Relatively easy to make. When they are empty I have always just thrown them away so I am in need. Anyway, I am wondering if anyone has the plastic trays and maybe the sleeves for SPP or SRP?
