A rough rule of thumb for a starting powder charge is 1.5 times the caliber, which is about 65 to 70 grains of 2F powder (Pyrodex RS) under a round ball. I would not go over 100 grains in a .45 caliber.
I had always heard the rule of thumb (again, general rule, not hard and fast doctrine) was starting load at one caliber, 45 grains in this case, and max load two calibers, or 90 grains in this case. I agree with everything else in post #2. But if I'm wrong, it probably isn't the first time.
