Just make sure your wads are properly lubricated with good BP wad lube so that your fouling remains soft, shot after shot.

I'm perfectly in agreement with Darryl on the cleaning.
I don't understand the assumption that 99++% of the worldwideweb shooting community has that it takes an hour to clean up blackpowder residue.

Cold water is all you need and it acts very quickly, very completely.

We had somewhere here on the site copies from an 1862 text on the service of blackpowder barrels after shooting.
No special chemicals, no hot water, no BS.
Just cold water and clean swabs.
Light oil afterwards and go about your business.

Furthermore, once you start burning blackpowder you'll never want to stop.
It's very rewarding.
