Anybody use this bullet in a 50 Cal inline with 100 gr Pyrodex(pellets) and 209 primer?

What kind of FPS out of the muzzle are you getting? How much bullet drop from 100-200 yards? Would you recommend this load for whitetail and mule deer? Really any thoughts, experiences much appreciated!!

Reason, i ask is we are having a little debate in our group.

thanks.
