As a reloader and I'm sure I am not alone. That there's always powders we keep an eye out for in are travels. My problem is when I go to a shop I always forget the powders I need or would like to try in a cartridge or many. Anyone make a list of the cartridges and the powder they need to stock up on or give a try. I'd like something simple I can keep in my wallet. I could list all my cartridges then list to the side what I need and what to try.maybe a number of letter system maybe better.
