My Hodgdon book lists the following for IMR 7828:

75 grain bullet...……...max load is 73 grains for muzzle velocity of 3824 FPS
87-90 grain bullet...…..max load of 71 grains for MV of 367 FPS
100 grain bullet...…….max load of 69 grains for MV of 3466 fps
117-120 grain bullet....max load of 67 grains for MV of 3324 fps

all starting loads are reduced 5 grains

Data manual # 26
I'd work up either powder but have not found any of the SSC powders from Hodgdon to be any different than the original powder.....except of course the length of the kernel
