Try two 50 grain Pyrodex pellets touched off with a Winchester 209 muzzle loader primer and a .45 caliber, 240 grain XTP in a Thompson Center Mag Express sabot. The bullets and sabots are sold together in packs of thirty. That's what I have found shoots the best out of my Pursuit.
Here's two different targets on what I believe to be 2 different range trips with that load.
Good luck.
