interchangeable .308 and 7.62X51 NATO

[Virgil]

Can I shoot the NATO 7.62X51 round in this LR308 Panther Arms rifle? I was told they are interchangeable rounds. True or False? What is the difference if not interchangeable?

You can. There is a pressure difference with 308 being a bit higher but with modern weapons it isn't an issue. There are some older military rifles that have an issue with 308, CETME is what comes to mind.

thank you for that info. I hear from another that the 7.62X54 would also work. Isn't that round a bit bigger in diameter?

That's incorrect, don't rely on that info. A simple comparison of the case dimensions will tell you all you need to know.

That's a Russian round, that 7.62 x 54.  You try to chamber one of those things in your gun, and successfully get it to go off - and we'll See You On The Other Side...   SYOTOS...

Great, NO 7.62X54 for me. and from what I am reading the 7.62X51 is ok, but not as strong of a hitter as the .308. Thinking I will buy the ones on sale, .308 or the 7.62X51. Getting hard to find both in my neighborhood. Any good on line places out there for reasonable ammo?

Absolutely true, when talking 308/7.62/51 its the opposite of the 223/5.56  where in the 5.56 is loaded to a higher pressure than its civilian counterpart the 223, in the case of the bigger round, the 308 is loaded to a higher pressure than the 7.62
