Caution should always be taken when using modern card and felt or fibre wads in original smoothbore muzzle loaders with Damascus barrels . You will find that most of commercial made wads are for modern breech loading cartridges and not for muzzle loaders. I prefer to cut my own with a punch or the right bore size, you will find that most original bore size has enlarged through use and modern wads are too small and will not give a proper gas seal
The over powder wad must be a 1/8 card of which if no felt or fibre wad is used then two 1/8 cards are best The felt or fibre modern wads are impregnated with a paraffin solution and have been known to be a fire risk. Has for plastic wads these should never be used in Damascus barrels where black powder is used because they are the first thing with the plastic build up in the bore to cause barrel ripple which I have come across many times The over shot wad must not be less than 1/16 inch .There are a lot of over shot wads on the market today that a for cartridges and are to thin. These wads are the most dangerous because when ramrod them home it happens many times that the ramrod by passes and leaves the wads on the bore wall it should be followed with a right size wad and bedded both down onto the shot. This is then a obstruction just has snow or mud in the muzzle and will burst or bulge a barrel so the motto is think safety, shoot safely .
