To start out with, it makes no difference what make or model musket you have. The problems and cures are all the same. At heart, a musket is a piece of wood with a mild steel tube for a barrel, a steel lock containing a few springs and moving parts, and some hardware.
Wood can burn, rot, splinter, stain, and break.
Some of these maladies are made more serious by the effects of firing your musket. Let's delve for a minute into the world of chemistry. It's relatively easy to make, but fortunately you have no need to, as the regiment provides your cartridge already made. When it's ignited and burned, black powder does two things that aggravate your problem. First, the flash burns off any protective coat of oil on the steel parts of your musket, particularly the area around the flash pan on the lock and barrel.
