100 gr. FFg is a good charge for deer, in a .54 ............. I use 120 in mine, but I like complete penetration and exit, if possible. If I ever got the chance to use it for bigger game - elk, moose, grizzly - I'd go to 160. My rifle handles that heavy a charge very well. I use a very tight ball patch combination on the initial load, then slightly looser for reloads, to make reloading quicker.

All good advice, Stan, thank you. In that vein, it would stand to reason that the hunting charge on the .62 rifle will be around 140-160 grains of FFG. Do you agree? In one of Sam Fadala's 1990s books he had a .62 rifle that he shot, and while I do not now recall the powder charge, in my memory that figure has been stashed away for future reference. Seems logical to me.
