They are/will seal tight. The only negative that I can think of with them, as a powder storage, is that they are clear. Powder comes in dark cotainers for a reason... powder does not like light. How long it takes for light, UV's, to work on powder I do not know. I use the tubes for a day @ the range, but I still use the 4-in-1 speed loaders for hunting.
