I'm looking, Tom - perhaps if 9.3x57 sees this thread, he'll respond. I looked and couldn't find it either and I know it's here. What's amazing, is the .45/70, 405gr. HP Lee mould bullet outperforms the .375
Swift A-frames and the big bullet's only running about 1,650fps at the muzzle. This is an easy load to duplicate for the double .45/70, running typical pressures OK for an original weak actioned .45/70.
