My point was that the 30-06 is under loaded and rated for a lower pressure by the SAAMI because of all the older 30-06 firearms still being used. Meaning softer and weaker steels in these older firearms.

And the Hodgdon's loading link below shows this for the cheap bastards like me who don't have a Pressure Trace system and strain gauges you glue to the barrel. And I have seen pressure test data for the .223 where factory ammunition only produced 49,000 psi and 6,000 psi lower than its SAAMI rated pressure.

And below is a good link "BUT" is still ballpark because brass hardness varies and thus base expansion above the extractor groove will vary also. (cheap bastards Pressure Trace system)

So my question to you is do you actually think your the only one who has ever heard of the SAAMI. Or would you have felt better if I quoted from my copy of Quickload.

So don't gauge my knowledge by my post count here, I'm 67 and have been reloading for well over 46 years.

And the link below I've had book marked for a long time, go to the bottom and read about the British base crusher system. The oiled cartridges actually registered up to 40% more bolt thrust. This is for the people who tell you to lube your cases to fireform them that nearly doubles the bolt thrust.
