What are the various 7.62 calbers? I see 7.62x39, and 7.62x54, but I'd like to know what the 39 and 54 represent.

Millimeters, the first is the diameter of the bullet itself, the second the length of the brass.

Millimeters. As in 7.62mm by 39mm and 7.62mm by 54mm.

7.62 X 63 =.30-06 Goverment
7.62 X 51 Nato = .308 Rem
7.62 X 25 Tokarev = .30 Mauser = 7.63 Mauser

hehehe...
I don't think I've ever heard of someone refering to a .30-06 Springfield as the .30-06 Government (although I could understand the designation) and never heard of the .308 Rem, though I do own a .308 Win/7.62NATO.

To answer the original post, there are many 7.62's because there are many .30 caliber cartridges in the world that each fill a different space in performance and needs.
This is probably my favorite non forum website concerning guns and ammunition:

7.62x25 Tokarev (Autopistol round)
7.62x28 Nagant (Russian gas-seal revolver cartridge)
7.62x39 Soviet M43 (As used in SKS and AK-47)
7.62x45 Czech (As used in VZ-52's during the Grenada invasion, etc)
7.62x51R (European name for our .30-30 Winchester)
7.62x51, aka 7.62mm NATO (Commercially known as .308 Winchester, they did the development, NOT Remington)
7.62x54R (Which some of us remember as the old .30 Russian round for the Mosin-Nagant rifle)
7.62x63 (European name for the .30-06 Springfield)


That's the first time I've heard the .30-06 referred to as the .30-06 Government, too. I've seen it listed as simply .30 Government, Model of 1906. I do, however, have plenty of .30-40 Krag brass headstamped .30 USA, meaning .30 U.S. Army.

Typically, when the boyz in da hood refer to "Busting a cap with their 7.62", they're talking about 7.62x39 Soviet M43 ammo. That's good to know in case you're working the ammo counter at Walmart and they come in looking for 7.62 rounds. You'll know what NOT to give them. :D

Yeah, just make sure to give them 7.62 x 51. :D

7.62x33 = .30 Carbine

The Nagant gas-seal is 7.62x38, not 28.

And, don't forget that in Finland, the 7.62x54R is known as 7.62x53R

Don't forget 7.62x33Kurtz as well.

Are you referring to the cartridge that was used in the German Stg.44? If so, it was 7.92x33, not 7.62x33. Just an FYI.

Indeed, you are right!

And it's kurz, not Kurtz.
Kurtz was the name of Marlon Brando in Apocalypse Now. :D

I'd like to add 7.62x67 = .300 WinMag.

Keep in mind that just because they say 7.62 they may be different diameters. 7.62 Nato uses .308" bullets while 7.62x54R uses .312" bullets (except when it uses .308" bullets--tee hee)

And the 7.62x39 uses .3105 bullets....

Perhaps I should have left the hyphen out of gas-seal as well, eh?

Just to be PITA and as something of a safety warning.

7.62 Nato and .308 Winchester are NOT always interchangeable.

Oh, the .30-40 Krag could also be called the 7.62x58 or 59 depending on which way you wanted to round. (case length is 2.314")

Actually, I guess they aren't. This came up in another discussion and I said the exact same thing. However, someone posted a link to SAAMI (http://www.saami.org/unsafe3.htm) and 7.62 NATO is NOT listed as unsafe to shoot in a .308 Winchester. You aren't supposed to shoot 5.56 in a .223, but it says nothing about 7.62 under .308. I'm still not sure why this is...

I stand corrected,
7.62mm X 63mm = .30-06 SPRINGFIELD
7.62mm X 51mm NATO ~ .308 WINCHESTER

Bore diameter on a 7.62 X 25 Tokarev = .309, and I wouldnt shoot it in a old Broomhandle .30 Mauser.

I do shoot 5.56 in my .223, and 7.62 in my .308, however.

.30 Government and .30 Army were often used as synonyms
for the .30-40 Krag as well as for the .30-06 Springfield.
The cartridges are very different.

I noticed Number6 listed the 7.62x33 as a synonym for
.30 carbine. I had a box of West German .30 carbine
head stamped 7.62x33; shot 'em all, saved only two
empties, back in the 1970s. Ah shoulda kept the box at least.

Check this item on my website for a whole list of different 'nominal' and 'actual' calibres, in both inch and metric, plus a load of other basic stuff on ammo: http://www.quarry.nildram.co.uk/Cartridges.htm
