I agree with Crigster, My OP also shoot the 50 cal, 245 gr Powerbelts very well.
I use 2 - 50 gr Pyrodex pellets (as recommended by CVA Technician via phone call).
The stock takes a bit of getting used to shooting off a bench, but is great for shooting from a 'normal' hunting position like sitting, standing, etc.
I took a nice whitetail doe during PAs early ML season.
But my true passion is the flinter. Cant wait til the primitive season comes in later this month.
