With supplies getting scarce, it's getting hard to find go to powders like Alliant Red/Green/Blue Dot & Universal. I do see the availability of the Hodgdon/IMR-Green/Red/Blue powders. Lots of talk about them on the interweb. "Green burns cleaner but is more dense", "use same loading data as Alliant powder". Then found a post about revised loading data using less powder because of pressure issues. What can you tell us about your experience with these powders? These would be use for shotgun, rifle & pistol cartridges with cast bullets. Mostly 12/20ga shot shells, 30-30w & 35R in the 150-160r bullets, 38/357 & 44mag. moderate loads. I also read "Alliant Unique and Hodgdon "Universal Clays" are nearly identical." What's your take? I have some experience reloading & am also now loading & shooting 35R with cast pistol bullets & 10gr Unique. I am now set up for shotgun reloading as well but am waiting on some components. I have also found a somewhat outdated Powder equivalent chart I'll post a screen shot of this as well: http://www.adi-powders.com.au/powder-equivalents/
