Has anyone tried Vectan A1 in 9mm Luger? I've found some locally at a very good price but reloading data for 9mm is next to non-existent. The burn rate for Vectan A1 is right between Win 231/HP-38 and Unique and the same as VV N330. It should be just fine but I'm concerned about lack of data. Is there something about this powder I'm not aware of or just one of those powders that has been largely ignored?
