Explain Bullets
 

Other than a .22 I have no experience.

If some one could explain why a .308 bullet can be shot with a 30.06 riffle?
I really have no clue.
Grains, calibers, loads ect......???

RE: Explain Bullets
 

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.

RE: Explain Bullets
 

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 .

RE: Explain Bullets
 

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.

RE: Explain Bullets
 

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.

RE: Explain Bullets
 

Wow, talk about a mouthfull....

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.

.38 S&W =.38&quot;
.380= .355&quot;
.38 special= .357&quot;
9mm Luger= .355
.357 magnum= .357
.38 Super= .355
9mm Makarov=.364&quot;

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.

RE: Explain Bullets
 

So basically all guns shoot a particular casing unique to that particular gun although some guns share the same bullet diameter. Correct?

RE: Explain Bullets
 

Here's a few more questions.

What is flat trajectory and is it something that you look for in bullet?

Partition vs ballistic tip pros and cons. Are there other options?

Boat tail?

Is 30-06 Sprgfld bullets different from 30-06?
I ask because only the 30-06 Sprgfld is listed here.

RE: Explain Bullets
 

All bullet trajectories are in an arc, not flat, dropping just after leaving the barrel. But you can use the word flatter in comparison of other cartridges. The flatter a bullet shoots, the less velocity it sheds, and retains more downrange energy and less drop. This is most desireable.

You mention some of the Nosler bullets: Partition bullets have just that, a copper division in the middle of the bullet so when the front half of lead expands or is broken away on impact, the solid lead filled bottom half of the bullet can still punch through. Good for use on larger animals or shots on bone and where deeper penetration is desired.

The Ballistic tip uses a poycarbonate tip to protect from deformity and give better aerodynamics to it. These bullets use a more fragile jacket without the partition to give more violent mushrooming, the plastic tip of the bullet is driven into the lead core to initiate expansion. Used for smaller thin skinned animals, when bone is hit, they tend to blow up in a big way. Lots of people I know who hunt deer, swear by these things for the gaping holes they create.

All bullet makers produce some sort of premium style bullets in popular weights and calibers to mimic what Nosler has done with their line.

30-06 is Springfield 30-06, named for the rifle for which it was originally chambered in. If you encounter something like 30-06 Improved, that's different from a 30-06 Springfield.

Herman_and_bill- I happened across a website just now that describes what happens when you fire a .308 in a 30-06 rifle. Kind of humorous if anything.

Briman, it was several years back and I did it on a dare,
I'm older now.

RE: Explain Bullets
 

I was at the range one day and a guy came with his latest purchase of a 1891 Mauser Carbine in what he was told was 7mm Mauser. So he proceded to try and get the gun sighted in at 50yards, no luck. So he put a target at 25yards and the bullets were everywhere. I started to look at his cases and noticed that he was shooting 7mm Mauser cartridges in an 8mm Mauser gun. I took one of the cartridges and tried to compare the end of the barrel to the bullet and it was quite sloppy. But it did fire.
