i have read that many shooters make their own by first finding a beauty salon supply shop where they purchase perm papers used when a lady gets her hair permed.
some shooters soak these papers in zippo liter fluid then let dry or just use them plain.
if you are shooting them from a paper cutter sharps closing the breech will slice off the back to expose the B.P. so i don't see any reason to make them more combustable....though some feel the need.
i'm gonna use them with making self combustable paper cartridges for b.p. revolvers. i have read that the ammo was made this way when these revolvers were in use.
hope this helps.
