Cartridge powder

[4V50 Gary]

Today I learned the Goex's Old Eynsford label has 1.5 F black powder. It's supposed to be for black powder cartridge rifles.

Can anyone please explain non-Eynsford cartridge powder. Where does in fall in the F scale?

I have an old can of Goex CTG, and compared to Goex FFg, it appears to be slightly larger granules, so, yeah, 1.5 Fg would be about right.

Pyrodex also once made a CTG granulation, but not for very long. I've been looking for a long time for an empty can to add to my powder can display.
