Raimey,
I'm not sure of the ballistics,but they are likely to be similar to 9.3x72R. It used a 193 grain bullet like the x72R. I would start with a starting load for the 9.3x72R, with the 193 gr bullet, and adjust it to "shoot to the sights".
To expand on Vic's( sharps 4590) advice( I do the same),if the balls you have on hand are a little too small, you can flatten them which will expand the diameter to make them fit.
