Jim,
Hodgdon's no. 26 manual shows data for HS-6 and HS-7 for the 300gr. bullet. I've not used either in my .454 but have had excellent results with both in .38 special, .41 and .44 magnums. I have found that the published velocities for Hodgdon's loads are a bit exaggerated when chronographed.
300 grain bullet:
Starting Loads Maximum Loads
Powder Grs. Vel. CUP Powder Grs. Vel. CUP
HS-6 15.0 1084 31100 HS-6 19.0 1450 46200
HS-7 16.0 1111 33400 HS-7 22.0 1501 50200
Hope this helps
Dave
