I currently shoot 240 grain T/C mag express sabots and T/C cheap shot sabots with 110 grains of 777. Precision Rifle's .44 cal. 260 grain Dead Center(expensive and must order in my area) sabots also shoot great. I plan to try some Black Mag powder after hunting season is over. The 777 shoots great but as MLKeith stated earlier, it does seem to cause a bad crud ring in my rifle.

I think you will be pleased with the Omega, especially after you shoot it!
