RC, I had used both Pyrodex and 777. I could not see the difference in any cleanup. Because they both degrade over time, I switched back to FFG Black Powder.
If MT does not permit the Powerbelts with a copper flash, they also sell Powerbelst without it.
My Hawkin does not shoot the Great Plains very well. Acceptable, but the 370 gr Maxiball does better. Go figure.
