Can you shoot .308 commercial ammo through this rifle? Yes. Is it a good idea? Absolutely not! If you are fond of your face. Use caution and stick to the NATO ammo.

Show me the evidence and I will retract my statement. Do you know something SAAMI doesn't?

OK, You win. You can absolutely safely shoot any and all .308 ammo out of any rifle with a 7.62 X 51 chamber! I now see it is true because some guy wrote a short article that is posted on the internet.

My God man! You do realize there are many variables to consider and telling someone to do something like this is, at best, irresponsible? I guess the liability laws in Newfoundland are more closely akin to European liability laws. Giving such information in the USA is ridiculously stupid. This site is based in the USA so the laws of the USA are the only ones that really matter. The owner of the site trusts me to help defray some of his liability from such ridiculous statements.

The rifle in question is nearly 100 years old and was never intended for .308 pressures. The barrel/chamber does not matter as much as the receiver/bolt. You can recut the chamber to .30-06 and single load the ammo, but the receiver was not designed to handle the stresses the .30-06 will apply. Just because you can, does not mean it is safe.

Please do not post such information in the future. It is irresponsible.

Dave, if you have a link showing where SAAMI has approved firing .308 Wimchester in a rifle chambered for 7.62 NATO, could you please share that with me?

Interchange indicates that it would go either way, and it does not (in my experience) Milspec in a .308, yes. .308 in a Milspec, no.

Please see attached- 7.62x51mm NATO or 308 Winchester? What's the Difference?

This thread has all the links and discussion.Can you shoot .308 in a 7.62 x 51 and vice versa? - WeTheArmed.com As a matter of fact all of the old mod 95 Chileans are sold at many different retailers here in Canada as .308. The main problem is people get hung up on CUP and PSI. They are not Interchangeable as measuring standards. The SAAMI interchange list is here. http://www.saami.org/specifications_and_information/publications/download/SAAMI_ITEM_211-Unsafe_Arms_and_Ammunition_Combinations.pdf

You can shoot what you like. I will shoot commercial 308 Win in a 7.62 marked bolt rifle any day.

Dave- the wiki article stated that it was safe to shoot 7.62x51 in a .308 Winchester chamber. It did not say safe to shoot .308 Winchester in a NATO chamber. Re: the ad- I have seen a ton of Ishapores up for sale, advertised as .308, and they are not.

If you run across the SAAMI reference that shows a 360 interchange is safe, I would really like to have it. The article I posted the link to (also by a Canadian gent) discusses the differences in the CHAMBERS of the two different calibers.

Thanks

Maybe you should read this thread. Surplusrifle Forum • View topic - 7.62 NATO Pressure vs. commercial 308 Winchester

He (Ganderite) worked for CIL which was the largest ammunition manufacturer in Canada. It feels like I am banging my head off the wall here. I am aware of the headspace/dimension differences. It is insignificant in a bolt rifle. I am done with this thread.

I think Dave said all I wanted to say, so all I am going to say is I use either & or in all my 7.62 & .308 rifles, same with my 5.56 & .223 rifles......

Dave, If you notice, Ed Hoffer disagreed w/ him. Ed's a pretty smart guy. What is the issue w/ caution w/ these old rifles? You do what you want w/ your rifles, but for someone not familiar don't you think caution is best?
