FFFG
You need to consult a Black Powder loading manual
Yes , but FFFG is recommended because it burns better in small cal. firearms.
Most recommend is 3F powder, either true black powder or the "synthetic" or black powder substitute equivalent and between 25 and 30 grains should due nicely.
yes, if they did it was the old black powder and ball muskets.
It would depend on caliber, for a .44 caliber you would use a .441 to .445 ball, for 36 cal use a .362 - .365 ball or conical bullet, You want to have your ball slightly larger than the chamber size so when seated you shave a thin ring as the ball is rammed into the cylinder chamber thus sealing the powder charge from moisture and cross fire and giving the best performance with your load.
a.69 cal
These were made to fire the .32 S&W revolver cartridge. Made well after the black powder era, they should be able to use standard present day ammo.
Yes
For a 44 cal pistol (not revolver) between 20 and 30 grains of 3F black powder or black powder substitute (like pyrodex or goex pinical) should do the trick. You will have to adjust the load to do what you want and to shoot the distance you want, but that should get you started. The above answer is stupid. Since most black powder pistols ARE revolvers. Fill the cylinder half full or a little more, if you do not want to play around with a grain counter,waste of time.
There is also a gun called a Black Power Revolver.
Either FFFg black powder or Pyrodex P may be used.
