Can you shoot 7.62x51 in a Remington 700 SPS 308?

The 7.62 NATO versus .308 Win debate has some parallels with the 5.56m / .223 Rem debate but in reality the rounds are closer and more interchangeable.
The pressure limits are set by different specifications but largely overlap. .308 Win probably has a higher working pressure limit by SAAMI spec in contrast to the 7.62x51. A bolt gun chambered in .308 Win has no special concerns. Some military surplus rifles in 7.62x51, especially if it does not have an adjustable gas plug, should be cautious in what .308 Win is fired in it.

You may see some max-spec .308 WIN labelled as "For Bolt Rifles Only", because it exceeds recommended working pressure for 7.62x51 chambered semi autos - although it's by no means unsafe or even a proof load - just more like +P as compared to NATO spec x51.

One thing to keep in mind: if you are shooting battle pack stuff like SA it is sealed with an asphaltic compound and may get the throat gummy.

But 1/2 of the Indian surplus was so bad with crushed necks, bullets that would fall out and a million other things that back in the day they could not give it away. Almost all of the other surplus was very good stuff and just about all of it was sealed with tar. Pull a USGI M80 round and see what ya find.![]()
I see you running, tell me what your running from
Nobody's coming, what ya do that was so wrong.
Also the Indian ammo like some of the Israeli surplus that was on the market had bad brass or lack there of. Helps to have the copper and Zinc mix properly and not have strings of copper throughout the "brass". Never had problems shooting tar sealed ammo through a FAL or CETME. SA ammo is some good stuff.
