Pistol or rifle? The ROUGH rule of thumb- start with the bore diameter. For a pistol, charge is 50% of the diameter- so about 16 grains of fffG. For a rifle, 100-200% of the bore- so 32-64 grains of fffG. You should check with the maker if they are still in business, and see if they have an instruction manual available. NEVER use anything but black powder, or a black powder substitute, such as Pyrodex.
Yes the difference in size is minimal you can cut off excess matirial after you start the ball in the bore if you want.
It is normally stamped on the barrel. If it is not, take it to a gunsmith. The smith can use a gauge or micrometer to measure the bore diameter, and tell you the right size ball and patch to use.

have a gunsmith do this, push a slug of close dia through the rifle, and micrometer the bullet. this will give the true bore size.
While the 4 gauge shotgun has a larger bore diameter, it was originally a black powder cartridge, and operates at much lower pressures than a modern high powered rifle. The 577 T Rex has much higher energy,

First, find a copy of the owner's manual for YOUR pistol. Second, use ONLY black powder, or a modern black powder substitute, such as Pyrodex. The ROUGH rule of thumb is one half the bore diameter in grains of powder. A .32 cal would use ABOUT 12-16 grains of powder.
Most black powder bores have a twist that is relatively slow. Say 1:36 or 1:50. They were 1:48 twist in 45 and 50 caliber
A musket is smooth bored, like a shotgun's bore. A rifle has rifling inside the bore (grooves).
Rifles were used in the American revolution most notably by Generals Daniel Morgan, and Nathaniel Green, who both used riflemen quite effectively. The rifle was not the most numerous weapon due to it'sexpense and training needed, the smooth bore musket was still the military weapon of choice and in the greatest supply.
Recoil is not necessary for a rifle to function. It is a by product of the mass of the projecticle being sent down the bore by expanding gases of burning gun powder.
