It is by far the most comprehensive and up to date list that I know of.

Now, seeing as you asked the question, if I were you I would google ".308 vs 7.62" and do some reading, but the generic, rule-of-thumb answer is 7.62 NATO is slightly hotter than commercial .308

I don't like how they list 5.56 with the .223 though.

.308 and 7.62x51 are pretty much the same, enough to be listed together, IMO, however, 5.56 and .223 are different enough that it can cause safety problems, and should be listed separately, also IMO.

For those who don't know, (As I'm pretty sure AndyC does, so this is not directed at him):
.223 can be fired in 5.56 chambered rifles, but do _not_ fire 5.56 in .223 chambered rifles. 5.56 operates at much higher pressures than a strict .223 chamber is rated for.
The cartridge also has a very slightly different size, externally, but has a Large difference in case wall thickness.
Most rifle bolts _will_ close on a 5.56 in a .223 chamber. This gives the illusion of "Oh, it closes, so it's safe to fire" Which is incorrect.
"Wylde" Chambered rifles are designed to shoot both.

Popping primers is a common occurrence when you're shooting 5.56 in a .223 rifle, this explains why ;)

This concludes today's session of .223 vs 5.56

I hate to rain on your parade but, the difference is not the cases or how "hot" the NATO ammunition is the difference is the LEADE or FREEBORE of the chamber. The NATO ammunition is loaded with longer heavier bullets requiring more leade in the chamber. .223 is usually loaded with short lighter bullets so the chamber is cut with less leade. The longer NATO ammunition will produce more pressure because the bullet is jammed against the rifling making starting it require more pressure. The Wylde chamber is a long leade chamber.

You will be helping to settle an argument... Thanks!

I can't see how - the symptom of primers backing out is typically caused by over-pressure or crap ammo.
