I'm new to black powder, but it seems in threads like this and others that the usage of 777 is the best propellant/easiest to clean also. Is this correct?
Each has its own peculularities. BH209 is harder to ignite than 777, requires tighter compression (tight sabot), and likes to put a hard residue in the breech plug flame channel. It is also far more expensive per shot. All of this is what I have gathered on here, I've never shot it myself.
Conversely, it requires much less swabbing when shooting, produces higher velocity with similar pressure, and is less sensitive to moisture.
If they were near the same price point and the ignition temp wasn't as high (I like my ACP conversion) I'd shoot BH209. Since they are not, I am content with 777.
