Tricky question. From what I can see probably 1550 to 1650 fps. Powder lot, age of powder, primer, tightness of your particular bore and other variables come into play. The only way to find out for sure is to shoot it over a chronograph. Every time you change any of the components you will have to do it again. As far as 200 yards I doubt you will get good accuracy. The bullet will likely be subsonic by the time it gets there and be very unstable. Pistol bullets have a terrible ballistic coefficient and shed velocity like crazy.
Trajectory is pretty steep also. My Strike , 2 inches high at 100 yards, is about 3 inches low at 150. This is based on actual shooting. Before you go launching slugs at game verify your POI at various ranges.
