Any gun store can sell you a commercial preparation which retards
barrel fowling in black powder weapons (I gather this is what is
meant by "antique guns"). I hope you aren't planning to fire an
antique without having it thouroughly checked out by a compentent
gunsmith! This could be very dangerous ....
Otherwise, in my black powder shooting days I used to use Crisco (or
equivalent) on patches. This worked fine but smelled a tad peculiar!
