A quick conversion of 230 MPa to PSI yields 33,358.7 PSI. SAAMI maximum average chamber pressure for the (non +P) 9 mm Luger is 35,000 PSI

In short, STANAG 4090 calls for NATO compliant 9x19 ammunition to be loaded to a lower maximum average chamber pressure that that permissible under SAAMI.

Hi,

Don is absolutely correct here, just as I was two or three months ago. You are just repeating your misunderstanding over and over with the hope that someone, anyone, will believe it. Don is right in suggesting that you spend more study time on this often misunderstood and somewhat confusing topic.

Also please check the warning label on each box of 9mm NATO ammo, commercially sold by Walmart, that warns that Winchester 9mm NATO is loaded to 10 to 15% higher pressure than commercial 9mm Luger cartridges. Your comments on Winchester's warning label are welcomed.


Respectfully,


Sieger
