Those propellants at American Reloaders are intriguing. I notice that they differentiate them somewhat by different calibers. I guess that it might be based on what caliber the propellants were pulled from. Their listing data for only one caliber per propellant makes me wonder about their interchangeability.
The 45 ACP powder #5 seems to be a direct substitute for Alliant Bullseye. The others, especially the 9mm propellants, seem more difficult to characterize. All the data is for 115 gr. projectiles, and none of the loads listed exceeded 1200 f/s, so they seem quite fast-burning. I'm STILL interested, though.
