There are many varieties of gunpowder.  Disregarding the military use of Composition B for large caliber,  high velocity guns - there are two basic types.  First there is 'black powder' - this is the form used up to the late 1800's and is still used in many applications, most notably among hobbyists firing replicas of antique guns.\n\nWhat is most commonly used today is nitrocellulose (AKA 'smokeless powder').  This comes in three different types:\n\nSingle Base: pure nitrocellulose\nDouble base: nitrocellulose and nitroglycerin\nTriple base: nitrocellulose, nitroglycerin and nitroguanidine\n\nNow these powders come in two basic types: pistol powders and rifle powders.  Pistol powders tend to be flattened cylinders of flakes in order to burn as rapidly as possible (gunpowder does not 'explode' it simply burns very rapidly while producing a large volume of hot gas).  Rifle powders tend to be tiny cylinders in order to produce a longer duration burn that provides steady acceleration down the longer barrel of a rifle.

chemically, nothing happens to the bullet itself.  the gunpowder exploding is however a chemical reaction. \n\nMechanically, a pressure builds up behind the bullet and starts pushing it down the barrell.  Some bores are smooth (shotguns) and the bullet goes straight down the barrell.  Some barrels have ridges cut on the inside in a spiral pattern that grip the bullet and put a spin on it.  This increases distance and reduces the effects of wind.  The bullet continues to accelerate down the barrell to the muzzle.  At the muzzle, the bullet has its maximum velocity as the pressure that has built up during hte gunpowder explosion is no longer confined by the barrell and the bullet, it gets released to the atmosphere.  The bullet will then travel on a trajectory that depends on its weight, initial angle of travel relative to the horizon, and muzzle velocity.  There is a whole science dedicated to this field of study called ballistics.  In general terms, the bullet will start sinking as it leaves the gun but its forward motion is much greater than its downward motion so the first couple hundred yards of a high powered hunting rifle is hardly noticable and just a couple inches.  However, as the bullet travels further, the atmosphere slows it down in the horizontal direction but gravity speeds it up in the verticle direction and it starts to sink faster and faster until it hits a target or the ground.

Found you a very informative site that goes into all performance categories with all bullet weights\n\nThe following article assumes the reader is familiar with the new .45GAP (Glock Auto Pistol) cartridge and the Glock 37 pistol which fires it.  There isn't room in this article to lay out the background, but it shouldn't take much effort on the reader's part to get up to speed on this new cartridge and the controversy between it and the .45ACP round that the gunzines are trying to create to beef up magazine sales.\nhttp://www.outdoors.net/site/features/feature.aspx+Forum+Firearms+ArticleCode+1117\n\nHope that helps.

The base of the bullet contains a small bit of phosphorous which is ignited by the burning gases from the ignition of the cartridge. This burns for as long as it takes the bullet to travel @400 meters. The tracer effect can be used under low light conditions to show you where your bullets are impacting (and the enemy to see where your bullets are coming from), allow you to 'designate' targets visually, and (to a limited extent) act as an incendiary device on inflammable materiel.

If fired straight up, no the terminal velocity is too small.  But if fired at an angle, the bullet maintains horizontal speed and that can be enough to kill.

Projectile range would be the equivalent of horizontal distance.\nThe forces involved are gravity (acting on the projectile's mass in the vertical direction), and the "push" from the initial thrust.\n\nAs the angle of the firing position increases above the horizontal, more of the initial push is used to combat gravity.\n\nIf the angle is too low, the projectile will meet the ground before it's maximum range (not enough action against gravity).\n\nFor most projectiles, the optimum angle is between 42 and 45 degrees (depending on the strength of the initial impetus). This is because the trajectory approximates a parabola.\n\nWith the given choices, the answer will have to be 45 degrees (answer B)...

One possibility would be frangible ammo, which won't penetrate through walls and is non-toxic (no lead).  I don't know if you can get rubber bullets anywhere, but that may be a bad idea (it would just make the intruder madder).\n\nhttp://www.precisionammo.com/\nhttp://accutecusa.com/\nhttp://www.precisioncartridge.com/frangible.html\nhttp://www.iccammo.com/products.html

None.  They are too obvious and make too much noise, and there's no telling where the round will stop.\nA .22 handgun is concealable, quiet and the round stops where you want it too.

Essentially, blanks are the regular cartridge, but instead of the shell (the pointy bit, otherwise known as the bullet), there is a round circle of cardboard.  The gun still fires as usual, but is much lighter (how arnold can shoot a big gun with one hand).  In theory, the cardboard should be burned and harmless, but for the first second or so, it's still dangerous.  So, it's a yes and no.  If you're wearing proper protective gear and are more than a foot from the person who's firing at you, you should be fine.  \n\nAn aside: A bullet has three main parts, the shell (the one that kills people) the cartridge (what holds the gunpowder) and a starter (what the hammer hits and what ignites the gunpowder).  For hollywood, if they show somebody loading bullets into a gun, they use bullets with deactivated starters, no gunpowder and regular shells.  Then, for firing, they use blanks.\n\nI would say that you should express your concern to whoever is running the wargames and see what they say.  they could be using a special setup, i don't know.  \n\nI know that was complicated, but best of luck!\n\n-Belril

I'm not sure who usually uses compressed nitrogen to shoot a bullet out of a gun.  Typical firearms use gunpowder, an explosive chemical mixture.  The bullet is propelled by the force of expanding gas in the explosion.\n\nPractically anything can be used to propel a bullet: explosive material, springs, leverage, compressed gases, etc.  The most powerful guns (those used on battleships and gun implacements) used plastic explosives to push their projectiles.  \n\nThere have been some experiments with using charged particles as a source of projectile propulsion.  The repulsive force between powerfully charged electromagnets can be INCREDIBLY powerful.  Theoretically, it should be possible, using current technology, to fire a small projectile at an appreciable fraction of the speed of light.  Obviously, this would take an enormous amount of money and some incredible engineering.

Depends on the powder charge behind it, the size and shape of the bullet and the rifling of the barrel from which it emerges.

Bullets are usually made of lead, with an outer shell of copper. Lead is a known carcinogen. It is not a good idea to mess with it, without the required permits and protection. I don't think it is worth the hassle.
