If you want the lightest possible load for a .454 w/H110 or WW296, simply use the 30,000CUP load data that is published for the .45 Colt for Ruger, T/C, etc.
Actually, 20 grains & a 360gr. bullet is pretty close, although your OAL might leave more room in the case than .45 Colt brass.
With that heavy of a bullet my experience would suggest you will not have any ignition problems, although it will certainly be a very light load for the Casull.
