I have a steel frame '58 Pietta' and the owner's states:
The starting load for a .454 round ball (44 Caliber) using FFFg is 12-15 grains.
The maximum load using FFFg is 35 grains and the max load using Pyrodex is 28 grains.
I personally think the starting load for FFFg is way too low, but that's what the manual says!
Man is the only animal on the planet that is capable of saying "I'm sorry." Further, he's the only one who creates the need to say it.
