I am not sure what you are looking for. Very light loads for the 300gr HC or loads that are like your hunting loads that are presumably heavy. :?
You can get a tremendous amount of loading data for the 454, both light and heavy, by going to Freedom Arms web site. However all of their data was developed with jacketed bullets.
Hodgdon developed TITEGROUP for the purpose of loading light loads in large pistol cases. If that's what your looking for they should be able to help. They sent me data for 240-250-260gr jacketed bullets @ moderate velocities with this powder. 10gr is all it takes to get bullets up to about 1,200 ft/sec and the loads are safe, unlike light loads of H110 or W296. Even 2400 should not be loaded to light.
I heard from another shooter who was loading 5gr of TITEGROUP behind a 255gr cast bullet so that his wife could enjoy shooting his 454.
