Anyone on here loading for this round? My preferred load at this time is 23.5 grains of SR-4759, behind the RCBS 400 grain SWC, cast of wheel weights and dropped into water right out of the mold. They should be right around 1000 fps. John Ross, the 500 guru, says SR-4759 is the perfect powder for the big Smith. This load kicks about like a hot .44 mag, and gives 1.5" or smaller groups at 25 yards. If I do my part just right it will sometimes clover-leaf 3 of the 5 rounds. He also says 100% loading density of slow powders like H322 & H335 will give around 1400 fps, with no chance of over pressuring the gun. What are some other loads you have tried? I know SR-4759 has been discontinued, but I bought up about 15 lbs and this should last me.
