This is the ammunition rule quoted directly from the SASS Handbook:
'The minimum standard for center-fire smokeless ammunition used in all SASS matches State, Regional, National, International, and World Championship Competitions is not less than a minimum power factor of 60 and no velocity may be less than 400 fps. The maximum velocity standard for revolvers is 1000 fps. The maximum velocity standard for rifles is 1400 fps. Pocket pistols, derringers, and long-range rifles are exempt from the power factor and velocity requirements'.
All of the help that you have received is excellent! And I will just add that you have to experiment to determine which bullet will perform exactly the way you want it to for this type of competition. Pay attention to the details of your work and you will arrive at the result you are expecting.
