    What are the effects of humidity on BP fouling? Is high humidity better or does dryness decrease the buildup?

    While black powder itself is not hydroscopic, black powder fouling is. It will absorb moisture out of the air which can cause soupy glop in ones pan if a flintlock among other potential issues of adding water to powder fouling, while still shooting, or if the gun needs to sit unfired for a bit after having been shot and reloaded.

    Depends on your definition of better. High humidity is a double edged sword. It keeps the fowling soft, which makes loading a bit easier, but as said above, it is easily absorbed by the powder residue which can cause problems in the flash pan of a flintlock. If you pay attention and wipe the flash pan often, you should not have a problem with it. On the other hand, low humidity will not soften the fowling and it can be more difficult to load after a few shots, and may require swabbing after each shot, and more prone to blocking the flash channel in percussion guns or the touch hole in a flintlock.

    No Deer has explained it.

    No contradiction. Softer fouling in the bore per op question. Soup in the pan is an additional observation.

    Meaning better for the goop. Worse for the rifle and shooter.

    Brokennock broke me neck....or nocked me down. :) What I meant was that you can fire more shots without cleaning in high humidity, than low. I remember an account of a rifle being demonstrated for an army, (the Ferguson perhaps?) and as it was a rainy or drizzling day, the rifle performed exceptionally well, as the humidity kept the fouling soft.

    +1 for my experience. In Louisiana, fouling stayed much softer than in Maryland.

    Myself, I would rather do a full cleaning between shots than sweat like a dog while doing anything other than physical labor/exercise. I have been spoilt rotten, I know. I would drop sweat in the pan off my forehead if I was still back in the mid-west.
