Can 7.62 NATO (or 7.62X51) ammo be safely used in a 308 Remington 700 rifle if the 7.62 NATO rounds are checked to be ok with a 308 headspace gage?

I shoot 7.62 NATO white box all day long for my once fired brass for my match loads.

No problems here. You will feel a slight more kick from the NATO than the 308 loads. Higher pressures I believe.

I personally only shoot 7.62 out of my M1A. I shoot .308 hunting ammo out of my .308 Remington 700P.

I'm sure you can I just choose not to.

correct me if im wrong (since im noob) but i think the rule of thumb is if it is chambered for .308 win, firing 7.62 nato will be fine...but for 223 rem and 5.56 nato, its the other way around

I know for certain that it's not a good idea at all to fire 5.56 NATO rounds in a 223 Remington rifle. But it's ok to fire 223 Remington in a 5.56 NATO chambered rifle.

But I don't know if this same rule applies to 380 Winchester.

that sounds about right...im just recalling a conversation i had with a gun store owner a couple months ago...and he said thats right for the 223 rem and 556 nato, but the opposite rule of thumb for 308 and 762.

and to add, my friend has an m1a which is chambered for .308 and he switches from .308 to 7.62 as he pleases, just depends on where he finds a better deal on which type of ammo haha

i have a remmy 700 in .308 too but haven't tried, but if it was the only ammo i had left i would definetely use them

SAAMI lists 7.62 NATO as safe to fire in commercial weapons chambered for 308 Win. They are both roughly a 2800 fps cartridge when using 150 gr. projectile. They may not be perfectly identical, but so close it won't make any difference in your bolt action. Where you'll find the problem is trying to fire reloads from brass that was originally fired through a military rifle. Many military rifles have more room in the headspace area of the chamber and the brass expands at the shoulder when fired. Trying to feed that brass into the much tighter tolerances of a bolt action will result in inability to close the bolt. Other than the reload issue, however, no problem.

I havnt really noticed it being harder to close the bolt on my reloads accept for when i seat one of the bullets too long. After resizing it should be fine and once firing in your rifle the neck should be fitted pretty well. Reason for once firing your brass in that rifle.

And here is that video I was talking about I was shooting my hand loads and my NATO.

The first 5 should be my hand loads then the next 5 are NATO then 5reloads. You can kinda see the more muzzle flip of the NATO when I go back to the reloads. The first 5 I have some flinch so don't mind those lol but you can also see I have no trouble closing the bolt with the reloads or NATO.

Don't mind my ex blasting away with the m4 and the wind moving the camera.

7.62x51 NATO ammo was loaded to lower pressures(~50,000 max psi) than commercial .308 winchester(~62,000 max psi). Firearms that are chambered for .308 winchester can fire 7.62x51, but firearms chambered for 7.62x51 should not be shot with commercial .308 winchester loads.

Yea those Winchester NATO loads are hot. My shoulder was screaming after 15 shots.

RugerNo 1, your answer is not quite correct. 7.62 NATO and 308 Win. specs for chamber pressure were measured in different ways that are do not relate to each other. Generally you are safe to fire 7.62 ammo in commercial 308 Win. rifles and generally you can fire 308 Win. ammo in 7.62 rifles. I say generally because there is no 7.62 ammo that is not made to .308 Win headspace specs. Read the answer on Fulton Armory's website for a more detailed explanation than I could ever give.

There, fixed it for you. :)

Actually the Nato and Winchester rounds are about the same pressure rating. Nato is 50,00 CUP which is very close to the 62,000 PSI equivalent of the Winchester. The pressure UNITS are labeled differently. The Nato cases are a little thicker.

I shoot both in my DPMS 308 which has a Nato 7.62 barrel and lower labeled 308. I believe someone said it all earlier that all of the NATO rounds are headspaced for 308 chambers. That really says it all.

Yes, I do stand partially corrected. Thank you.

:facepalm: Yep, I failed to remember that as well.

Additionally, if I remember correctly(my information is secondhand, perhaps out of date as well), Cold War era 7.62 NATO was loaded to lower pressures to ensure working in the various NATO firearms across the world. As we all know, pressures in one rifle may not be safe in another, so NATO specified a lower pressure load (perhaps that is why I was thinking 50,000 psi...) so that the various member countries could share ammo if the need arose.

fired six rounds ot of a 700 bdl. HAD A VERY HARD TIME EXTRACTING THE SPENT CASE.

Edit: Why it was 5.56!!!!

Since you asked about 7.62 nato in a 308 I guess I was silly to think you would read my mind and think I was shooting 7.62.

I'll let you shoot my Winchester rounds and then my hand loads. Then you tell me the NATO stuff is softer lol my shoulder will beg to differ.

I shot some Malaysian 7.62 out of my 700BBDL, bolt started to stick after 40 rounds. The Malaysian rounds were de-linked ammo.

Usually you have to resize the neck as it expands during firing.

You need fairly warm loads to fireform, from my experience.

You're not following through with your shots in that video. ;)

This was my understanding...

I use NATO brass and a 5% reduced load (per loading manual) for the M1A, due to the reduced case capacity because of the difference in wall thickness. Something like M80 ball is loaded with the correct powder for the M14 gas system. I suspect most commercial 308 and 30-06 powder is pretty slow...too slow for an M1, for example, which is why companies are now offering M1 specific loads. They've increased the burn rate to something closer to what the military ammo used.

Ishapore 2A1 rifles are generally considered to be unsafe to fire commercial 308, but 7.62 NATO is perfectly fine.
