My first ML was a Knight LK-II, 50 cal, percussion. I've killed so many deer with it, I've lost count. I know of at least 3 at 100 yds., 6 at 150 yds, 1 at 186 yds and 1 at 200 yds and several more from 25 to 80 yds. 240, 250, 260 gr. saboted bullets, #11 percussion cap and 85 gr. Tripple 7 - 2f or 3f. Both work great but the 3f burns a little cleaner.
