Marco, wanna see some interesting stuff?

Check out the .308 Win. max average pressure numbers in the following SAAMI document.

Then check out the 7.62mm NATO max average pressure numbers in this military document:

Compare the numbers and terms for pressure.

Then do the same thing with the .223 Rem. in the SAAMI one and the 5.56 NATO one in the military one.
