Quick reply,
Any greasy lube will foul more than spit patch. A spit patch "cleans on the way down,IF done soon enough after shooting. Dont buy into the "season the bore" sales gimick.
Use greasy lubes when hunting,Water base will freeze to the barrel. Also will dry out in a short time.
Cut at the muzzle gaurantee's that the ball is centered. If you cut yourself,learn to use a knife!
