Howdy all -
I've posted a couple of powder/published data questions on sixguns and I really haven't had an answer regarding loading data pertaining to Universal Clays and Unique. My understanding, which originated here, is substituting Universal Clays, grain for grain, with published Unique data is safe. The benefits of using Universal are easier metering and cleaner (unbelievably was the term used) burning. So far so good. My Hodgdon's #27 manual lists a max charge of 8.5 grs. Universal for @ 255 gr. slug. The Hodgdon's #26 manual lists a max charge of 11.5 grs. of Unique for a 260 slug. Respondents at sixguns tell me NOT to go over the published max of 8.5 grs. Universal in the #27 but no one is commenting about the 11.5 gr. charge published in the #26. The max loads from each manual is three grains apart and for a fast burning powder, that's huge! I do not wish to tempt fate by throwing caution to the wind and pump out 30,000+ CUP loads using Universal. I would like to use a powder that gives me the flexibility to load in the 850-1050 fps range with acceptable pressure and accuracy. Is this unrealistic using either Universal or Unique??
