To make things as simple as possible .308" is a bullet diameter or caliber.The bullet is the actual projectile while the assembly is called a cartridge.Many cartridges use the same caliber bullets but have different shell casings so they are named different.The difference in capacity and design of the shell casings are the reasons for different velocities.For example the following cartridges are all .308 caliber and use the same bullet
300savage
308win
30-06
300wsm
300h&h mag
308norma mag
300win mag
300ultramag
The same is true for the .284 caliber .These cartridges are .284 caliber and use the same .284 caliber bullet.
7x57
7mm-08
284win
280 rem
7mmrem mag
7mmwsm
7mmstw
I hope this gives you an idea as to the difference between a caliber and a cartridge.The caliber is the bullet diameter and all cartridges of equal caliber can use the same bullets.
grains is a measurement used to desribe the weight of the bullet and is used by reloaders to measure powder charges.
Stubble pretty well covered it . There are 7000 grains in a pound if that helps any ,lets you figure how many loads you can get from a pound of powder .
first you must make the distinction between a bullet and a cartridge. a bullet is not a loaded round of ammo it is simply the lead/copper incased lead etc thing that goes out the barrel. not the whole thing

I couldn't even hope to approach the answers you just got. But I am surprised that nobody said this yet. DO NOT ATTEMPT TO FIRE THE .308 round from your .30-06 rifle. The bullet (as stubblejumper stated) can be removed from a .308 and loaded into a .30-06 casing, but the cartridge is not interchangable.
The caliber designation refers to the diameter of the bullet in inches. A .308 bullet measures .308 inches across. A 270 bullet is .277 inches, 7mm isn't really 7mm's it's .284 inches. A 50 caliber bullet is 1/2 inch or .50 inches.

Where to begin...I think the bullet/projectile diameter thing has been covered. Although, truth be told, you're taking your own life in your hands if you're shooting .308 bullets loaded in a .30-06 case, because it seems that you are refering to the cartridge .308 win bullet instead of .308" bullet which would be correct. The .308 win shoots a .311" bullet, which would create HIGH PRESSURES when fired out of a .30-06 case into a .300/.308 (lands/grooves) barrel.
THe .308 round will load in a .30-06 because the .308 winchester was designed with the .30-06 case as a template/starting off point...the rebated rim is the same dimensions, so it will feed just fine, but WILL NOT HEADSPACE, meaning that the neck and shoulder of the cartridge is not contacting anything at the chamber mouth. It seems that on occasion one will fire and be just fine, but it isn't going to happen in my gun, I'll guarantee you that!!!
Screw the 10 ring, keep them in the zero!!!

Not quite. You might be confusing the .308 (7.62 Nato) for the 7.62x39 or 7.62x54 which both have a bullet diameter of .311. The .308 has a .308 diameter bullet just like the 30-06.
As Nomercy said, putting a .308 cartridge in a 30-06 rifle will probably not go off, but if it did it would most likely cause extensive damage to rifle and shooter.
If you are really looking for a bit of confusion about bullet sizes take a look at handgun cartridges.
Alcohol, Tobacco, and Firearms... who's bringing the chips?

Not to recommend it, but I have done it.
If the 06 chamber is tight enough it will headspace the 308.
Its not extremely accurate, but there was no damage either,
I just ended up with some fireformed cases that had a very short neck.
