I would look into a 200 grain Shockwave and try to get 120 charge accuracy at least under it.
Sound advice there! I currently shoot a 200 gr. T/C Shockwave in the blue sabots out of a .50 Omega with a 110 gr. charge of Triple Se7en ffg. loose powder. Sighted for 3" high @ 100 yds, this load is only about 2-3" low @ 200 yds! This would make an EXCELLENT antelope load IMO! Good luck!
