Stone,
What buffer you are using makes no difference to peak pressure if it was in battery - It is not a blowback system like in a submachine gun. By the time the bullet has passed the gas port and unlocking occurs, that's when the buffer make s a difference. By then the pressure will have dropped way below what it takes to blow a hole in a case. The buffer will influence things like harsh extraction from early unlocking but again, the pressures indicative of what you experienced rule the buffer out as the cause.
