SAAMI Max pressure for the .223 is 55,000 PSI, not 62,000 PSI.
The two cases are identical. The biggest difference is that 5.56NATO is used in MG's. And the Remington very rarely.
EPVAT(Electronic Pressure Velocity and Action Time) and SCATP are just different methods of measuring. SCATP is basically the same as SAAMI. Difference between 'em is 114 PSI.
"...the great CUP/PSI conversion..." There is no mathematical way of doing that. They're different methods of physically taking the pressure.
Go here, about half way down for a good explanation.
