    The 308 is a shorter version of the 30.06 right? Now... can I shot a 308 round on a 30.06 chambered bolt rifle? Just wondering guys. No insults, no jokes. (Well jokes are ok)

    No no you can not...it would probably explode I'm guessing.....although depending on the bullet diameter it MIGHT go through the barrel...but it would probably **** alot of stuff up....and well get you killed.

    Basically from what I understand .308 is just the standardization of all the Allies and Axis's bullets so they would all use the same round....easier to get ammo...etc.

    30.06 is an American classic so that's really the only reason why it's still around.

    Take the time to understand the rounds then your post would have been prevented.

    I suggest you do a Google search and study the term "headspace".

    Yes you could chamber a 308 into a 30-06 and pull the trigger. Would it work all that well? I doubt it. These cartridges headspace off the shoulder if that is wrong Your BANG turns into a BOOM. If you fired a 308 in an 06 chamber then the shoulder and neck would expand splitting the case causing powder and gases to spew from the chamber towards your face and eyes. You may end up with a bullet stuck in the barrel and may need to push it out (The same direction as it is going). Hammering on the tip of a bullet that is meant to EXPAND is not a good idea in my book.

    The case head is the same dimension on the 308 and 30-06 and that is .473" other than that and the bullet diameter of .308" the dimension's are different.

    The barrel/receiver is stamped .30-06 and not .308 WIN for a reason.

    Can I run .45 LC in my 1911? The bullets are the same diameter, but one case is a little longer than the other. It should work, right?

    Well, he DID say this within his post.

    As I am sure you have deduced. The .308 is a SHORT ACTION cartridge. The .30-06 is a Long Action Cartridge.

    They are not interchangable. Ever. Not even for fun, once. :cool:

    Running with scissors is much safer. ;)

    How do load the scissors into the chamber??

    Same way as you do bullets.

    Pointy end towards the bad guy.

    308 and 30-06 are pretty close in power and ballistics. the purpose of the 308 was to take advantage of more efficient ball powders and make the case smaller but retain the same power as the 30-06 allowing troops to carry more ammunition for the weight.

    the 30-06 can be loaded easier due to the larger case and 30 caliber bullets of many types that work with the .308 for handloading work with the 30-06. the 30-06 case is more friendly to handloaders than the 308 due solely to case size.

    Sad part is, I've seen this before at the range. A guy shooting .308 out of a .30-06. We questioned him because of the odd report. Stopped him as soon as we saw the cases on the ground. Many people are dangerous because they don't know the 1st thing about their firearm, and have no business w/ a firearm. Arrogance will get them a quick face change or worse. Asking questions is a great way to learn. When It comes to firearms, don't "try" a cartridge that is different than what the firearm is designed for. Some revolvers can use different cartridges, but that is it.

    Headspacing is a concept that all shooters should at least be familiar with. Different cartridges have visibly different designs that are used to headspace the cartridge in the chamber.
    Rimmed - one of the earliest designs. The base is stepped up larger than the body of the case (see .30-30, .38 Spl, .44 Mag). These cartridges headspace on the rim. Length is not a critical factor with in reason.

    Rimless - This can be subdivided into two categories
    Bottlenecked and straight walled]

    Bottlenecked Rimless is by far the most common rifle cartridge design. All that I know of (except the .357 Sig) head space on the shoulder. The angled area between the neck and the body. Overall length is not critical (once again within reason). The length between the base and the "datum line" ( a fancy word for the mid point of the shoulder) is critical.

    Straight walled rimless - (9mm, .40 S&W and .45 ACP) Most cartridges of this design are used in autoloading handguns. They all headspace on the mouth of the case. Length IS critical (some tolerance allowed). You cannot chamber a 9mm Luger cartridge in a .380 (9mm short) gun partially because it is too long.

    The others are semi-rimless (.38 Super, .32 ACP) than can headspace on the mouth or the rim and belted. Most belted cases are magnum rifle cases. Most headspace on the belt (with the notable exception of the .450 Marlin that headspaces on the shoulder. The belt was added to prevent if from being chambered in weaker .45-70 rifles.

    The .308 is "based" on the .30-06 but if you look closely at Asmel's diagrams, there are a number of dimensional differences. Will a .308 chamber in a .30-06? Yes. Will it fire? Almost assuredly. Is it a good idea? Absolutely not for several reasons.

    Headspace. Since the .30-06 shoulder is is MUCH farther from the base, the .308 cartridge shoulder will not rest against the shoulder of the chamber. The extractor on the bolt will hold the case against the bolt face. In the case of a push feed mechanism like the Remington 700, it is not likely to hold the case and simply allow it to fall into the over length chamber. The extractor "may" hold the case securely enough to let the firing pin strike the primer. When that happens, the base will be several thousandths of an inch from full contact with the bolt face. This is called excessive headspace and can lead to all kinds of problems. When the expanding gasses from the burning powder start to increase the chamber pressure (in about a thousanth of a second) the brass expands until it reaches the steel chamber walls. The pressure then pushes the bullet out of the mouth of the case toward the rifling (in about another thousanth of a second). Because the shoulder is not in contact with the chamber, it too moves forward toward the rifling expanding the shoulder toward the chamber walls as it goes. Finally the bullet is released by the case (at an unpredictable place) and the bullet moves toward the rifling. There is a high likelyhood some of these expanding gasses will escape ahead of the bullet. Some will likely leak around the case toward the bolt face (because the case could not expand as designed) and toward your face. With the case rattling around inside the chamber as pressures get into the tens of thousands of PSI, all sorts of bad things can happen like blown primers (leaking high pressure gasses toward your eye), blown cases, broken extractors and firing pins, separated case heads leaving the neck in the chamber and rendering the rifle useless.

    Can you? Sure. Should you? Hell no!
