I already know the answer to that question, No, but I am looking for a chart to help me find as few powders as I need to cover the range of cartridges I can reload from 9mm pistol to Lapua 338 rifle. I can find a single powder that lists various charges for several calibers (the powder co has that chart). I can find a chart that lists all the powders that can be used for a particuler cartridge (Modern Reloading by Lee has that). But what I want is a chart that lists all powders down the left column and across the page, check marks for cartridges that can be loaded by that powder.
Yes, I am aware that experimentation could expand that chart, it would not cover ALL posibilities.
Why do I want it, because if TSHTF I want to be able to load ALL mycartridges from as few different powders as possible. I dont want to carry a pound or two for each gun I have. Then I can go buy 3 or 4 cans of powder and know all my reloading is covered.
The data is out there, has anyone compiled it into a single chart? If not then I can see a project to keep me bussy during this pandemic. But I dont want to waste my time if it has already been done.
