Can I buy a 30-06 hunting rifle and shoot 7.62 NATO rounds in it?

I've long heard you could but.....

Is getting a gun that shoots 7.62 still a good plan?

My early days of survivalism, the standard was to get .45, .223 and 7.62, because that was what the U.S. Military used (And the Soviets?). The assumption was that when the commie hoards invaded those calibers would be more available than any other round.

Should I be thinking in a different direction, in the 21st century?

You can get a chamber adapter to use .308 or 7.62X51 NATO in your .30-06 rifle. The Navy did this with M-1 Garands when we went NATO standard. You lose some accuracy as the bullet will "jump the unrifled gap" the chamber adapter creates. The adapter fits tightly in the chamber and requires a broken shell remover to remove from the chamber.

I don't mean to offend anyone by my next comment, but I am just calling it like I see it.

I have been on this board for a while now and see alot of talk on this board about "7.62" and/or "5.56", and it is obvious that most, if not all, of the questions originate from folks who probably have little or no gun experience. I have a couple of friends who fall into the same catagory and worry themselves sick about ammo compatability.

I literally own a safe full of guns in a wide range of calibers including 308 and 223, and I have never bought or fired a "7.62" or "5.56" round in any of my guns. When I buy ammo, I buy "308" or "223", and I have had no trouble finding those calibers anywhere I have ever shopped.

I will offer a warning though. If you intend to buy a gun, you had better buy your ammo NOW, and I mean buy it cheap and stack it deep. The time around the 2008 election was a bad time to be trying to stock up on ammunition, and I predict it to be the same in 2012.

My brother and I both have a pretty good stock pile of ammo, and I reload and am well stocked on reloading components. We were talking this week about "investing" up to $5000 each in additional ammo in common calibers (22 lr, 9mm, 45 acp, 223, 308, 30-06). My brother's idea is to sell it if/when the prices go up, but I have never been able to make myself part with any of my ammo.:cool:

the technical answer is yes you can.

But it would be a bad idea

the 06 and 308 are based off the 8mm mauser case they all have the same base and taper the difference is the length and in the mauser's case bullet diameter

so what will happen is you can put a 308 in your rifle it will feed and chamber but the difference is there will be a 12mm gap in the barrel wich can damage your rifle and ruin the throat of the bore

Back in the day .30-06 was the standard 7.62mm round. Actually a .30-06 is a 7.62x63mm. Now 7.62 NATO refers to a 7.62x51mm round or what we know as a .308. Is it possible, this is the first I am hearing of it so I don't doubt that you can, but I would caution using ammunition in a gun that was not chambered for that particular round. You can use the same lead and bullet eights as you would in either round, they are the same. Believe it or not with like bullet weights the ballistics between the two rounds is pretty similar.

Once you install a chamber adaptor in 30.06 it is supposed to be permanent.
The US Navy (Sm Arms Section Crane Naval Wpns Ctr) came up with that idea first and they found out quick that the adaptor and the empty case has a bad habit of coming out of the M1 together and the next round blew the 7.62 NATO case almost to a straight wall.

I have seen guys take 7.62 NATO and fire it in 30.06 on several occasions and while no failures occurred the practice is not encouraged.

The original Navy adaptors were never designed to be inserted/removed by user.

At the same time Springfield Armory (the real one ran by the gov't at Springfield, Mass) tooled up and made M1 Garand barrels in 7.62 NATO chamber. I have a M1 with a 7.62 chambered barrel on it. As well many M1 Garand Match rifles have been chambered for 7.62 Match and I have had several of them as well.

Now that being said there is a 7.62X39 Adaptor that can be add but now you are going to be running corrosive ammo for the most part in your 30.06 and that opens a whole new can of worms but its a long process to fire, remove, punch out case, install another round and reload it in your rifle and for me that is not acceptable. Not only will it ruin your barrel if not cared for quickly and effectively but the accuracy on the stuff is poor as compared to 30.06 ammo loaded properly.

As others have indicated the bullet jump will be considerable and should be avoided IMHO.

I assume you have a line on a 30.06 rifle at a good price so the easiest thing to do is get the 30.06 and learn to reload which a 5th grader can do. I was loading my own ammo in 5th grade but my Dad had me with him loading with him watching me in the 3rd grade. One thing about 30.06 every gun shop,department store, hardware store etc has 30.06 and generally 30-30. The 30.06 is far superior to the 30-30 as your effective range is much further and the bolt action rifle will hold up longer than a lever gun and is much easier to work on from a gunsmith perspective and gives much high long term system life.

Or buy a 308 rifle and get 308/7.62 ammo but be advised milspec 30.06/7.62X51/7.62X39 is not the most accurate ammo on the market either as the military accuracy requirements are designed to get plenty of ammo through inspection without failure for accuracy and a multitude of other requirements such as waterproofing, ingnition reliability, controlled pressure range etc. As well most states don't allow military ammo to be used in hunting for several reasons. Years ago milsurp ammo was quite cheap and plentiful and commercial vendors could sell more ammo and make a bigger profit if the military was outlawed for hunting. The "rationale" used to get the laws passed was military spec ammo came in and out leaving small holes and did not give the wound lethality of commercial ammo and this was "gospel" for years till the Army Wound Ballistic Lab was established in the 80s and the whole wound ballistic world theory was disproven by Dr. Col Martin Fackler. You can googe his name and read about his work for the next five years.

Again handloading ammo will give best accuracy for hunting ammo. There is 30.06 and 308, and 7.62 MATCH ammo loaded every day by the industry and gov't but harder to find.

As well there are videos that will take you through the reloading process and show you what to do. I can generally teach folks how to load in a couple of hours once they get their bench set up and tooling. There are much cheaper hand loading kits from Lee but I don't use them personally.

Of the selections I would personally take the 30.06 and stay with it as the variety of bullets it will fire run from 110 to 220 grains in bullet weights. For average hunting of medium game bullets in the 150 grain weight range will do you fine. In 308 you are restricted to 110 to 190 grain and the velocity will be about 100 fps slower.

Depending on the size of your chamber you can reload a case from 3 to 150 times. The industry chambers are designed to take a wide variation of case sizes and allow cases to expand upwards of .008" on firing. This is where US milspec brass will be beneficial and it will normally take far more reloadings than commercial cases as they are lighter which translates into thinner case walls.

My target rifles expand the base dimension no more than .004" and some .002" and give long life.

I can reload 53 different calibers and the only commercial ammo I have bought in years is 22LR and 22 Mag.

Where did people get the idea that most 7.62x39 is corrosive? Did it used to be that way? I've hardly ever seen it(mostly just the surplus Yugo on stripper clips), and never in an actual store.

In whatever I get, I was planning to go semi-auto.

As it would be more useful in a firefight. Not that I expect to get into a firefight, just thinking of the possibility post SHTF.

A bolt action is fine in combat against a single deer. But the slow firing rate would be a handicap against several raiders armed with ARs.

If you are going to go through all this work why not just re-barrel the .30-06 to .308? Some .30-06 barrels even have enough diameter to be set back and re-chambered .308.

I had a Navy surplus chamber insert and I used it in an old Mauser that was chambered in .30-06. The instructions said that it could be removed with a "Stuck Cartridge Remover" included with the insert. Well, I can assure you that I was never able to get it back out after the first shot. I would trust it in a bolt action but, I would be leery of using it in a self -loader because of the reason stated by someone else above. It could extract and eject with a spent case. It could happen in a bolt action bit, you may have a chance to notice it if it happened.

Buy a .308 ShellbackBill.:thumb:

Oh brother. 7.62x51 and .308 are the same thing! Just like 5.56x45 and .223 are the same thing. The only difference between them is that each of the NATO rounds (7.62 and 5.56) are loaded hotter per NATO specs.

Get a good .308 Remington bolt action rifle. For example, Remington 700 SPS Tactical is a wonderful rifle for around 500.00 new.

.308 is 7.62mm x 51mm.

.30-06 is 7.62mm x 63mm.

You cannot shoot these different calibers in the same action.
