I just helped my best friend get a Bighorn to shoot, according to my notes[ because the season starts on the 13th] and we did not have much time or opertunity to work on it we tried what I consider the standard starting loads for a Knight. First we got both 44 and 45 cal bullets and a bunch of different sabots we took the breach plug out and tried the different sabots to see how they fit. We ended up with the regular knight sabots, then out tohis back yard we tried the loads a lot of people use in Knights, 90 gr 777-FF and two RS pellets both shot tight enough groups for his hunting about 1 inch at 85 yds; work on it some more after he gets his deer.
