This is possibly a dumb question to most of you but...
is the 7.62x39 the same as the .223 ?? I don't know much about military rounds as you might have guest.
 
.223 is equal to 5.56mm
.30 is equal to 7.62mm

amongst other differences, as well.

edit - the phrase 'equal to' is actually incorrect, now that i think about it. "similar to" is a better way to define it.
 
Also note that the military designated rounds (come advertised as 5.56x45, not .233) fire with higher pressures. Might not be so great to use in your .223 chamber. Depends on the gun.
 
Right - the answer is no, although they're both so-called 'intermediate-powered', or 'assault-rifle' cartridges, they are quite different, with the .223 rem (or 5.56mm NATO or 5.56x45mm) round sending a 55-62 grain, .224 caliber bullet out at 3000 to 3100 fps, whereas the Russian 7.62x39mm sends a 123 grain, .311 caliber bullet out at about 2350 fps. The other Russian round, not to be confused with the first 2 mentioned here, is the one originally made for the AK74 rifle, and that is the round known as 5.45x39mm, which is essentially the same case as the 7.62x39mm, but necked down to take a .221 caliber bullet. It has ballistics similar to the .223, of around 50-55 gr bullets going out at around 2900 fps, IIRC.
 
Same category of rounds, called intermediates. Somewhere between a pistol and things like the '06 and 8mm and so on.

Other than that, no similiarities. .223 is roughly the same thign as 5.56x45 (minor variations in pressure, case thickness, etc). The number before the x refers to the bore size. .223 is 5.56mm, 7.62 is 7.62mm. The number after the x is case length, so 7.62x39 uses a case that is 39mm long to fire a 7.62mm wide projectile. The .223, or 5.56x45, uses a 45mm case to shoot a 5.56mm wide projectile.

Clear as mud?
 
Good question, Commisar. I would be inclined to think that they are not, as they were still originally designed as pistol rounds, but I don't know.

To me, they just aren't there, to the power level required to be a rifle cartridge.

Come on--you need to make it clear when you're being sarcastic. A few years from now this quote will be popping up on these forums and in gun stores as if it's gospel.
 
JohnKSa - I think you must have thought jefnvk was addressing the original question, but he was addressing the post by Commissar Gribb. The rounds mentioned in that post were/are pistol rounds (Tokarev and Five-seveN).
 
close but not eh? thanks guys I haven't bought eather yet, just looking for something cheap and easy to find to play with.

They are very close, butjust remember to buy whatever your rifle is chambered for. 5.56 won't do a number on some guns, while it will on others. If I were you, I wouldn't be one to take chances on it, seeing money isn't that abundant (for me at least)

You are both absolutely correct. My sincere apologies to jefnvk for responding to his post without taking the time to do so intelligently.
