Thanks to Kirpi97 and HiBC.
Kirpi97: When you say you load 20-25 grains, do you mean that you load (actually weigh the charge of powder) 20-25 grains of Pyrodex and not the equivalent volume of 20-25 grains of blackpowder? This is where I got confused. Hogdon says Pyrodex is less dense than blackpowder but has more energy (they didn't say whether this was based on mass or volume). Another article I've read suggests that Pyrodex FffG loads need to be reduced to 85% of the blackpowder weight (since it is less dense, the volume may be equal?).
I load metallic cartridges and have for 30+ years so the "dump some in / fill it up" loading technique sure seems a little strange. I have yet to blow anything up and don't really need to be able to tell that story.
Thanks again.
