Can anyone tell me where to find loading data for the 45-60 rifle using smokeless powder?

Can anyone tell me where to find loading data for the 45-60 rifle using smokeless powder?

T.A.P., The only data I have is what the fella that I bought mine from used, and it seems to work pretty well. Start about 5% to 10% lower and work up. I use 300 grains lead ahead of 25.2 grains of IMR 4198. It's not a heavy load, but shoots to point of aim. 2 1/2" to 3" at 100 Yards. Never got around to working up a load for accuracy, as it's only been used to shoot steel plates. Hope this will get you on the paper.
