Powder Valley has Norma 203B in-stock right now, which is VERY close to Reloder 15. - Some say they are the same powder. - I wont say because I don't really know. - But it's there (and a few other Norma powders) if you want to try it.Been watching for some RL15,16,17 and 19, it is always out of stock. Has anybody seen any? Maybe I am watching the wrong retailers.
