Protection against powder gases, bullet fragments, etc..
With a muzzleloading firearm, it is CRITICAL that the bullet be seated against the powder charge, with no air space between the two (blown up guns result). By marking the ramrod, you can use the ramrod to measure if the bullet is fully seated.
Let's discuss some terms. GRAINS used in this context is a measure of weight. The weight will depend on WHICH powder is used, and WHICH weight bullet is used. It may vary from 4.5 grains to 12 grains. For your own safety, NO ONE should ask for load data from an open site such as Wikianswers. For all you can tell, I am 11 years old, and Mom does not know I am on the computer. (I'm not, and she knows) PLEASE obtain load data from the powder and bullet maker sites- trusted data.
Modern bullets can be loaded by a hobbyist at home with the rights materials and equipment. The general process is this: Starting with the brass casing, insert a new primer into the primer hole at the base of the shell. Weigh out the exact amount of powder using a specialized scale that weighs in grains (one seven thousandth of a pound). Insert the powder. Tamp the powder down with a press. Some bullets require a separator between the powder and bullet such as wax or cloth. Finally the bullet is pressed into place. Obviously this process is very general and should not be attempted without the right tools and materials, with precise instructions.
I'm not sure what you mean by "truest" smokeless powder. If you mean "which powder will emit the least amount of smoke when you shoot" then answer isn't that easy. The amount of smoke depends on the conditions of combustion such as burning rate, chamber pressure and quantity of powder. A small quantity of fast burning powder would emit less smoke than a large amount of slow burning powder. If the goal is to find the load for a given caliber that will smoke least, in general you should look for the fastest burning powder that is recommended for loading that caliber and bullet weight.
If you have ordered questions into bullet points then each question (or bullet point) should end with a question mark.
Yes you should do.
Know Your Muzzleloader. Primitive hunting arms include the muzzleloader ... Black powder is the onlytype of powder that should be used in muzzleloaders
No, it cannot. The maximum amount of heat that a human body can generate at the skin level is around 110 degrees fahrenheit. This is far below the temperature range which would cause spontaneous ignition of the propellant in a modern bullet. Even black powder won't ignite at that low a temperature.It is possible for a bullet to discharge by the force of a body falling on it, but that is extremely unlikely.(and remember, when you say "bullet", what you really should say is "cartridge" - the "bullet" is only the lead/steel portion being expelled out the front, while "cartridge" includes the brass body and propellant as well).
Baking powder and bicarbonate of soda are abrasive and should not be used to brush the teeth.
A bullet to the head.
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.
