It takes about 6 years for bio bb's to break down completely.

No, its not a good idea to reuse, them because reused ones can have particles of dust and dirt that will inherently get picked up when fired. Its also a bad idea to use low quality BB's cause they tend to have a seam around them from molding, and both them and the re-used BB's can jam the gun.

if you need to find some really inexpensive BB's that are really high quality, no seams, and come in high quantities, i get all of the ones that i use from www.airsplat.com. I really love them, they are really precise.

Just about any major airsoft retail store. my top picks are airsoft gi and evike but just about any other airsoft website will stock them (unless of course you want tlsfx pyrotechnic grenades, they mainly sell those in GB). Just go on the websites and search "airsoft grenades".

Depends on the angle at which the bullet hits the water. At a shallow angle (less than 45 degrees) the bullet may bounce off the water, just as if it had hit a hard surface. At more direct angles, the bullet will splash, and may be deflected from a straight path. It will stop fairly quickly due to the resistance of the water.

There is no one answer to your question- otherwise there would be only one 9mm pistol made. It ill be the weapon that YOU shoot best, and is the most reliable in functioning. I am partial to the Browning Hi Power, other people prefer the Glock, some like the Sig, some S&W, some Mauser, Walther, Colt, etc. If you are shopping for a handgun, find a shooting range that rents guns for use of the range, and try as many as you can.

12 Guage is the least expensive ammo. It is the most commonly used. For most common loads 20 guage can easily be found at the same prices.

NO!!!!!!!!!!!!!!!!! DO NOT TRY THIS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Full sized .30 caliber cartridge, developed in 1906.

None. A primer does not contain propellant powder- it contains an explosive that ignites the powder. If you mean how much propellant powder is in a 9mm cartridge, that will depend on which 9mm cartridge (there are nearly a dozen different 9mms) which weight bullet, and which powder. My basic reload data table for 9mm Parabellum (9mm Luger) is 3 pages of data with different powders, bullets, etc. A basic load is 4.5 grains of Bullseye powder with a 115 grain bullet.

Yes

It is possible, but extremely rare, to survive a gunshot wound to the head.

There isn't a difference. Mainly because .38 Special IS the standard .38.

The "Special" in .38 Special is simply a marketing word. The term was used to distinguish it from the earlier .38 Colt, which is now obsolete.

In modern terminology a ".38" is an abbreviation of .38 Special.

Now, just in case you did not ask the question you meant to...

Another common question is the difference between .38 Special and .357 Magnum. The .357 Magnum was designed as an "enhanced" version of the .38 Special allowing more powder to be stored in the casing and thus deliver more power to propel the bullet. The .357 Magnum is much more powerful and has much higher gas pressures, and thus it is not safe to shoot a .357 Magnum out of a gun designed for .38 Special. Fortunately most modern .38 Special revolvers are designed so that the longer .357 Magnum will not fit in the cylinder. The reverse however is permissible as .38 Special can be fired in a gun intended for .357 Magnum because the magnum-gun is built much more sturdily than required to shoot a .38 Special.
