24 to 28 grains of black power.
Chances are that if you overload the charge in a revolver style black powder pistol, you can blow up the cylinder or blow the barrel off the end of the gun.
There are none produced that I know of, a 209 primer would be over kill in a revolver due to the small chamber and lower amounts of powder.
FFFG
Chain fire, powder getting wet...
22-72
The BATFE website has the answer.
Yes it is concealed, but not illegal because black powder firearms are not considered a "firearm".
In the technical sense no it is not loaded via the muzzle of the gun, black powder revolver is accurate as terms go, but they do fall under the blanket of "muzzle loader" in general terms.
The value of ANY gun is based on the exact make, model, and condition. The Baby Hammerless was not a derringer, but a very tiny revolver with a folding trigger. The value of those revolvers runs about $200 for a working specimen in fair condition. Do NOT attempt to fire this with modern high speed 22 Shorts- it was made for black powder cartridges. Better condition can equal higher prices.
The question makes no sense.
Yes , but FFFG is recommended because it burns better in small cal. firearms.
black power or cartridge rounds? Colt made the first "practical" revolver, so this was the first commercially successful cartridge revolver. I can't say about black powder... but you should read this: http://en.wikipedia.org/wiki/Revolver <><><> The first Colt revolvers were black powder handguns. The self contained cartridge was invented later.
