In a quiet side street not far from where the Texas freeway system knits the sprawling suburbs of Houston into something like a city centre, business is booming at the Top Gun shooting range.
Recession is not biting here in the oil-rich Energy Capital of the World as it is in the rest of the United States - but that is not the only reason why it is difficult to find a parking space outside Top Gun towards the end of the working day.

"What's the Difference between .308 Winchester & 7.62x51mm NATO?"
7.62x54mm is also known as 7.62 Russian. Tokarev and Dragunovs fire this round.
I've got a FAL, and I'd never feed it 7.62x54 ammo.
It was just a typo...45 to 54 instead of 51.
The only thing I know that shoots 7.62x45 is the Czech Vz.52/Vz.57 rifles.
Can't say if the extractor is different in them from any other AK type, but it won't matter to the .223 vs. 5.56 issue. The throat is the distance in the chamber from where the shoulder of the round stops against the metal of the barrel and where the rifling starts. It's shorter in .233 Remington. So if you load a 5.56 in a gun chambered for the .223 round the bullet might possibly be forced into the rifling. That could cause some seriously high pressures to develop. Not good.
In the gun chambered for 5.56 the worse that will happen is a decrease in accuracy as the bullet jumps a too wide gap before engaging the rifling. In a practical sense, I don't think it will matter much for everyday shooting. Definitely not in am AK rifle. They shoot real good and for a long time, but they are not known for their accuracy. ;)
