    As i am trying to learn more about guns, it seems to me there is alot to know about what your shooting. Is there a difference in quality of bullets? How much do they usaully cost? What are the diferent sizes of bullets?
    thanks for any info on the subject...

    This is a HUGE subject,more than what we can really get into here. There are rimfire,and centerfire cartridges. rimfire are usually .22 caliber. Caliber is the diameter of the bullet measured in hundredths of an inch. Centerfire have a primer in the middle of the back of the case,and are usually larger caliber,ie. ,45 cal. The firing pin strikes the primer,igniting it,which in turn ignites the powder,expanding the burning gasses thousands of times to create pressure to send the projectile,(bullet) down the bore. Next time we'll get into bullet design. Questions?

    Bullets range from .17 to .50 caliber for cartidges. Black powder and shotgun slugs get even bigger. Bullet size is measured either as a fraction of an inch or millimeters. A .30-06 has a bullet about .30" wide, an 8mm Mauser bullet is about 8mm wide. Bullets come in many different weights and shapes, as well as sizes. I suggest you try a web search in Google or Dogpile using key words such as bullet, ballistics, caliber, nose, and other related terms. I am sure bullet manufacturers like Speer and Hornady have a lot of information on their websites. Use key words like speer and bullets or hornady and bullets. Search engines are great for getting info like this. Dogpile is at www.dogpile.com . Google is at www.google.com. Once you learn how to use the search engines, you can find out almost anything.

    Here's a basic definition of caliber:
    When you see numbers like 22 caliber and 30 caliber, that means roughly .22 and .30 inches. When you see numbers like 6.5mm and 8mm, that means something roughly similar in milimeters.
    But it gets a little more complicated...
    Technically caliber means width of the bullet. But it tends to be used for different cartridges as well. Also, people have a way of estimating a little too much in their terminology, and if you don't know what they're talking about, you may get confused.
    7.62mm = 0.300000 inches. But the term 30 caliber is used to include practically everything under 8mm. Most 30 caliber bullets are .308"wide (.30-30 Krag, .30 carbine, .300 Savage, .30-06, .308, .300 Win Mag, .300 Weatherby Mag, .300 Remington Ultra Mag, 7.82 Lazzeroni Warbird, etc...) Some are not, however, some are .311 (7.62x39mm Soviet, 7.62x54mm Russian, .303 Enfield). Also, beware the metric designations. 9mm Luger and .380 Auto are both .355", while 9mm Makarov is .364". Some numbers are way off, like .444 Marlin and .44 Rem Mag are .429" Some are right on, like .40 S&W (far as I know).
    Next, when you see a military cartridge, numbers may look like 7.62x51mm NATO or 8x56R. The first number is the bullet width, the second is the length of the empty case. Some cartridges have other explanations. .30-06 Springfield means 30 caliber, adopted in 1906. .30-30 means 30 caliber, with 30 grains of powder (not sure whether that number's for black powder or smokeless). 250-3000 means 25 caliber, moving at 3000fps. 22-250 means 22 caliber, based on the 250-3000 case.
    Basically, cartridge designations are names, not specs (usually).

    As far as interchanging cartridges goes, the answer is NO 99% of the time. You CANNOT fire .308 Win in a gun chambered for .30-06. You CANNOT fire 40S&W in a 10mm gun.
    Here are the only exceptions that I know of. They are so because the cases are exactly alike, straight, and basically just turn part of the chamber into barrel. Usually, one can fit into another's chamber, but not the other way around.
    .38 Special will fit into the longer chamber of .357 Rem Mag.
    .38 Special and .357 Rem Mag will fit in a .357 Maximum Chamber
    .44 Special will fit in .44 Rem Mag.
    45-70 will fit in a 457 Wild West magnum.
    .22 short will fit in a .22 Long Rifle chamber

    When handloading, you can use bullets that are slightly smaller than the original, but not the other way around. You can use .308 caliber bullets in a gun chambered for .311, like an SKS, AK, Mosin Nagant, or Enfield.

    It is even more complicated when you get into using bullets with particular firearms. The barrel twist in the firearm has to have the right match for the bullet or it will not shoot well. The bullet has to be stabilized when it leaves the barrel, if not it will tend to wobble and tip in flight, usually making for an inaccurate shot.

    Fortunately overstabilization of bullets is usually not a problem so smaller bullets normally can be fired from faster twist barrels (however some thin varmint bullets will not handle the forces put on them from a rapidly twistingbarrel and will shed their jackets in flight) There is a wide range of bullets that will be stabilized by common barrels, but be aware if you are planning on hunting larger game with heavy bullets then often a firearm made for varminting may not handle the longer bullet well.
