I have acquired these bullets but can not find any data to load them. I also am having trouble using the new search tool in finding any threads that may help. Closest data found was for 190 gr. cast in the Lee manual with Accurate powders only of which I only have one of them and it's 2520. I'd rather use something a Hodgdon, IMR, Winchester or Alliant powder as they're easier to find locally. These will be fired in a Marlin 336 20" micro-groove. Thanks in advance.
