I bought a Black Mt. Mag (about 230 bucks new). Took it to the range and worked up a load (using sabots and pyrodex pellets/powder) with no problem. Best workable load seems to be 100 grains with at least 260 grain sabot. I had been admiring the rifle for a couple when T/C discontinued it so I got it on sale. Has a hammer action but bored for sabots (!:28 twist). Oh yeah I switched out the no. 11 plug for a musket cap.
