Personally, the best long range load I have used is the 250 grain T/C Shockwave ahead of 130 grains of Pyrodex Pellets. Using three 50 grain pellets is a little faster - and may work in your gun - but I got better accuracy with 130 grains (two fifties and a thirty). Sight in 3" high at 100 yards and you should be only about 6" low at 200 yards. Good luck. Roscoe.
