Yes but a 7.62 x 51 is not exactly the same as a .308 from some of the gun forums I've been on. I've heard that damage could be done to your rifle using the surplus 7.62.x 51 rounds in a .308 rifle. Is this in fact true or is it safe to use them?

I've never seen surplus 7.62 x 51. I've seen lots of 7.62 x 39, which is what the AK shoots.

Wierd, since we don't have a lot of weapons that use that round anymore. I think the M14 still uses it, as does the M240B, and the M60 used to. With the 240 and the 60, though, the ammo would be linked, which doesn't translate well to surplus sales.

It's still used as a sniper round.

What kind of firearm are you thinking of shooting the 7.62 x 51 round in? What kind of shape is it in? |

This is my personal experience, so take it for what it is.
I have yet to have successfully blasted 5.56/7.62NATO ammo (not reloads) through my .223/.308 rifles. Every time I tried, within a round or two possibly three at most, the brass would swell and stuck in the chamber. I literally had to kick the bolt handle back to extract. This happened with good quality surplus GI ammo or First World surplus ammo and not Russian/Chinese steel case ammo. .223 and .308 on the other hand; even reloads (quality reloads from people who knew what they're doing), went through my military semiautos just fine.

Due to manufacturing tolerances, every chamber is going to be slightly different; depending on how the chamber go/nogo tolerances between the .308 and the 7.62 overlap on your specific rifle. Your .308 rifle may not work with certain ammo. The 7.62 chamber tolerances were set generous for a reason; so that they could shoot a variety of ammo found at hand from different manufactures in different NATO countries. Sporter .308 dimensions are tighter, allowing for less tolerance to specific ammo, especially reloads. That's just the way it is. If your .308 rifle won't digest 7.62 ammo, hot or cold... don't use it. If you are shooting .308's in a 7.62, watch for base thinning. You may even want to mic a couple of fired cases to see how much case stretch you are getting. Much beyond .007-8 and you are getting into case failure range.
