I guess I am not sure on that
. I have a bunch to store in a variety of calibers. They will do for now but I bet I eventually make up some kind of racks that do not require alternating the dies.
After doing some digging around I found a gasket sealed container that I think I am going to make a tray to fit inside. The Lee tray will also fit inside it.
Listed dimensions on this container are 11.5 x 8.5 x 6.5. The biggest dia lock nuts I see in my collection are Lee Hex at 1.3" across the corners. Making a tray out of say 1/4" Oak Veneer plywood to hold 8 dies wide by 6 dies deep may work out well. More or less 8 calibers per box. Might end up only 7 calibers due to taper in the box, we will see.
Cheapest price I found was on Maomart website. Six of them for $52.

Maybe use something like this to space the plywood up off the bottom of the containers. Might be easier to make those on the lathe and drill-tap for 10-32, then part off to exact length needed, bolt to the plywood with flathead 10-32 screws.
