Yes, if you are an adult.
No, they may not.
Not unless it was manufactured prior to 1898 and is classified as an antique.The problem with owning one even then is that under 18 USC, felons are not permitted to possess explosives, and black powder is an explosive. Therefore, even if you lawfully owned a genuine antique, you could not legally poossess the powder to fire it.
The questions is not "Black Powder", More it is a question of the definitions of a firearm and of a pistol. CT law would consider a black powder pistol a firearm because it can fire a projectile and the barrel length would also fall under the definition of a pistol. Below is a decision made in CT from the law library. "Replica antique pistol, which fired a .44 caliber ball propelled by a black powder charge, instead of a bullet from a fixed cartridge, constituted a weapon under section; defendant's claim of implicit "antique gun exception" to prohibitions of section rejected. 49 CS 248."

No. A felon in any state is not allowed to possess any type of gun, regardless of if it is loaded or if ammo is available.
A quick check of the CT game regulations indicates that NO handgun may be used for deer or turkey hunting. Black powder or modern. Run a Google search for Connecticut Hunting regulations, and take a look.
Manganese dioxide (MnO2) is a black powder.
Black powder absorbs moisture from the atmosphere
Under FEDERAL law, yes- if it is a caplock or flintlock (no 209 primer guns) HOWEVER- state laws vary. Some states permit, some prohibit. Georgia does not permit a felon to possess a muzzleloader (includes ball & cap) Virginia permits, but does not allow a felon to possess black powder. #209 primers (shot shell primers) are considered ammunition under Federal law, and a felon may not possess ammunition.
Black powder and smokeless powder differ significantly in power. Smokeless powder is more powerful, providing higher velocities and energy compared to black powder. Smokeless powder's cleaner burn and increased efficiency make it the standard propellant for modern firearms, offering better performance and reduced fouling.
does not matter once the Powder has starch it turns black and the powder can be any color
Black powder, or a black powder substitute such as Pyrodex. Smokeless powder (modern gun powder) should not be used in a traditional muzzle loading firearm.
