7.62x39 is a cartridge. It fires a 7.62mm (.30 caliber) bullet. 7.62mm is the diameter of the bullet and 39mm is the length of the casing. It is the common AK/SKS cartridge. It is called a 7.62 Soviet to differentiate it from the 7.62x51 NATO round commonly called a .308 Winchester in civilian circles.

7.62x39
It is what it is. 7.62x39 is a military round that does not interchange with another 'civilian' type of round, such as 308 or 223.
7.62x39 is however not that very difficult to buy. If your friend would like to sell the rifle, I am interested.

Wrong. 7.62 is the caliber. 7.62x39 is the name of a cartridge or chambering. Let's see you load a 7.62x39 in a 7.62x51 rifle and see what happens. Both are the same caliber rifle, yet fire completely different cartridges.

Or load the 7.62X39 in a Mosin Nagant M44. Or the 7.62X54R Mosin Nagant round into the AK or SKS. It won't fit in them as it is quite a bit larger a round while shooting about the same caliber bullet. The 7.62X54R is so much bigger that a 7.62X39 with bullet barely is as long as the case is of the 54R.

Actually, 7.62 mm equates to .308 inch.

Actually if you want to get technical, you're technically wrong. 7.62mm equals .300 inches. .308 inches equals 7.82mm (the true bullet diameter a 7.62x51mm NATO cartridge.) 7.62x39mm and 7.62x54mmR cartridges actually have a true bullet diameter of 7.92mm. Why? Not a clue. Simplicity in naming I would assume.

This is also part of the answer. When you divide the 7.62 by 25.4mm/inch you get .3, which is essentially .308---these numbers are the diameter of the bullet. This also holds true for any of the caliber notations whether they are in metric (mm) or english (.000) units, which are a fraction of 1inch--ie .308 is almost 1/3 of an inch. It is actually 7.83 mm.
As more obvious example, look at a 9mm cartridge and a 38 cartridge and you will note that both bullets are about the same diameter--they may look different and be on top of different cartridges but their diameters are about the same. 9mm divided by 25.4 mm/inch is around .35ths of an inch whereas a 38 bullet is .38ths of an inch; so they may have different velocities and power and shapes based on the cartridge length and amount of gunpowder,and the actual shape, they are almost the same diameter.

Not in a 7.62X54R. There it equals .311".:biggrin:
Listing of the 7.62 round bullets.
7.62X25 = .309"
7.62X33 = .308" <---.30 Carbine
7.62X38R = .295"
7.62X39 = .311" <--- AK round
7.62X45 = .304"
7.62X51 = .308" <---- NATO designation of the .308" Winchester
7.62X51R = .308" <--- .30-'30 Winchester
.303 British = .3125"
.30-'06 = .308" <----- round used in the 1903A3 Springfield
7.55X55 = .308"
7.62X54R = .311" <--- Mosin Nagant Round
Now is everyone confused as to 7.62 rounds?:laugh:
Military Cartridge Diagrams shows many of the cartridge and bullet measurements.
