I've got streaks/crud/? in the barrel in several places. They seem to be mostly in the angle where the lands and grooves meet and are mostly about 6 inches from the muzzle.
The gun is a Traditions Pa. Pellet Flintlock. I was shooting both Hornady XTP's and cast SWC in Harvester sabots over loose Pyrodex with 4F black in the pan. I shot and cleaned a lot this fall and can't recall seeing the streaks then. I didn't fire it during the late Pa. flintlock season. I unloaded by unscrewing the breechplug and driving the bullet out the back.
I've cleaned with hot soapy water, Shooters Choice, and left it soak all afternoon with Birchwood Casey foaming cleaner in it. The streaks still remain.
Plastic fouling? What do I clean with for that? Or something else in there? Thanks,
Dale
