7.62x39 vs .308

Guys, please help me out!
My friend insists that the 7.62x39 is a necked down .308! I told him that he's nuts! I hope that you guys can post something in my behalf to convince him that I'm right. He won't listen to me.....

Your friend doesn't know what he's talking about.

I was going to type a long post explaining the difference between the two rounds, but I realized that he could figure it all out in about 5 minutes with a search engine on the internet.

Necked down????

That would be hard since there almost the same diamater so that puts him in the :barf: class.
Both are good rounds for what they were intended but to say the AK round is a necked down 308 is just plane WRONG

A .243 and 7mm-08 (short .284) are necked down .308s, all part of the short action club. x39s are shorter cartridges--perhaps "super short action" - very similar to .30-30s.

Well, not really. the NATO 7.62x51 uses a .308" diameter bullet, and the Russian M43 7.62x39 uses a .3105/.311 diameter bullet. Close, but not the same.

Certainly, tho, there's no logic in the statement that one is derived form the other in any way.

Your friend has to check out a local AA meeting When a cartridge is "necked down", the bullet it will take is smaller - necking down a .308 will therefore produce a cartridge that uses smaller than .30 caliber bullets - 7.62x39? - wrong. It is also nominally a .30 caliber cartridge, so even without delving into all the ballistics and loading information, that just doesn't make any sense.

When I saw the title of this thread I thought: "You've got to be kidding...right?"

There is no comparison between the two...the .308 is far superior. I agree with CarbineCaleb...maybe he should check into AA .

7.62x39 comes from a family of Russian cartridges that started with .220 Russian. The PPC series of cartridges is frome the same family. All are about 1.515 in length and have a smaller diameter head than .308. They are not even close in dimension to each other. Interestingly U.S. military is moving toward adopting a new round to replace the .223--something like 6.8X41MM based on the old 30 Remington round, similiar to the 7.62x39.

Ask him what the bullet diameter of the .308 is in millimeters.

I think you guys have made the point. Now at least he won't hear it from me, but all you guys who offer specifics and examples. Sometimes it takes hearing it from a stranger and not a friend.
Thanks loads.

Its a remarkable statement given that the M1943 round was invented in the 1940's after Russian experince of the German 7.92Kurtz assault rifle, and the 7.62mmNATO was designed in the 1950's.....
