Call Hodgdon and ask. There were loads listed in many of the old Dupont/IMR manuals using the CCI209 primers. They seemed to have added lots of data for Rio and Fiocchi primers and may have deleted a lot for the CCI primers in the online manuals. They are a decent primer, but primers are not usually interchangeable. You can't say "Just use data for primer X with primer Y". Call your powder manufacturer and get their advice. I would usually suggest using data for the hottest primer for the components you are using and then dropping the charge a half grain or more. The definition of "Hottest" primer being the one that develops the highest pressures with the least amount of powder, using the components you intend to use. Sometimes primers perform differently with different components. powders, and hulls. Look at currently published data to sort that out and go from there. I also look for a resulting pressure of less than 10,000 PSI. If working with unknowns, that threshold will be lower.
