The grains of a bullet, be it black powder or not , is the weight of the bullet. Lets say you have a .50 caliber rifle, and fire a 250 grain bullet at a target and hit dead center. Then fire a 300 grain bullet, that bullet will hit slightly lower on the target , but will have more force or stopping power" due to the weight. So the higher the grain the heaver the bullet.
7,000 grains in one pound
ABOUT 15.1 grains to a gram.
I believe 3 grains of black powder for a start
You can buy them at Buffalo Arms.
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.
black powder is usually measured by volume, 180 is more powerful, the higher the number the more powder there is and thus the more potential energy stored.
You need to consult a Black Powder loading manual
Typically 50 to 75 grains of ffG powder.
Depends on who made it.
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.
The .44 S&W Special is a cartridge currently loaded with smokeless powder, as opposed to earlier cartridges such as the .44 Colt or .44 Russian. Those cartridges, generally considered obsolete, were loaded with black powder. Smokeless powder should not be used in firearms built for black powder- the pressures are too high to do so safely. You may also find .44 caliber BULLETS (not cartridges) intended for use in a black powder revolver. These are typically made of a very soft type of lead, different from the harder lead alloys (lead-tin-antimony) used in modern firearms.
By all means, yes they can. If you are referring to modern bullets or self contained cartridges the answer is no. Black powder guns fall into two major categories, muzzle loading and black powder cartridge, With muzzle loaders the powder is poured in the barrel topped with a patched lead ball or bullet, and ignited by an external cap or flint and steel. BP cartridges are much like modern bullets with the exception of the powder. Black powder burns at a slower rate thus the pressure within the case is less.. Modern "smokeless powder" burns rapidly when contained within the shell casing and produces higher pressures and bullet velocities.
