Well I was shocked about some of the things they mentioned, even though they wished to appear as if well versed in the workings of a muzzleloader.
That graphite sounds like the way to go. I have a small tube with graphite dust in it. The directions state to clean all surfaces, and then dust only the moving parts. Sounds like it should work. After all my Knight Disc has a firing pin, as does my Genesis.
Now all of us remember to throw that ramrod down the bore on top of the projectile..

The last time I remember reading about that practice was when they loaded muskets in the civil war. They would bounce the steel ramrod three or more times to seat every thing, and then fire.
