The .30-40 Krag was a US copy of the .303 so the data would be identical. I think that you will find AR2206H too slow for cast lead. I am getting good results with reduced loads, around the 2,000 fps with jacketed projectiles in both the .30-40 and the .303. I have some cast loads in the blocks using IMR4198 that have yet to be fired.

IMR4759 is also suitable for reduced loads being a bulky powder. Hogdon publish loads for 30-40 Krag but not for some reason 303B. There may be some around still
