Black powder pressure rarely gets about 5000 p.s.i. in most gauges so that is not a huge concern. I have loaded black powder with both card and fiber wads and plastic wads for over 20 years. If I'm hunting I prefer plastic wads because I will be taking fewer shots. If I'm shooting clays I prefer fiber wads as this cuts down on the fouling considerably.
