There are some .005 patches around that should make a snug fit. I know a couple of guys that shoot no patch . That may work for you. It would be tight after 1 shot.
I measured some fabric yesterday and even light Muslim is still about .008. When you double that it takes you up to .546 still snug but doable. I f it was my gun I would get a .520 mold . But I shoot my smooth bore at least once a month.
