If you really need to shoot 200yds then try the 50/40 200gr Shock Wave,it shoots out of my Omega with 3 x 500gr Pyrodex pellets avg is 2300 fps I sight in 3 inches high at 100yds and it POI at 200 is about 4 inches low.
Only in one particular spot do I need this, 200yd shots are actully fairly rare and you need to set up for them and pratice them to be able to do it right and if you have a wind forget it. Lee
