I looked back into my the Lee manual and found an article in there about calculating reduced loads. Has anyone tried Lee's formula? It seems rather complex, but if it works, it works. The only problem I can see with it (just from reading it, not trying it), would be the possibility of starting out with a charge of a powder that is below published minimums for that powder.
