There is no flaw in my logic, the .270 is a necked down 30-06 case and loaded to 65,000 psi.

The next thing your going to say is the Remington 700 chambered in 30-06 I have is made of lower grade steel.

Or that my Remington 760 should not have been chambered in the higher pressure .270 Win.

There is no flaw when the SAAMI selects a lower chamber pressure due to the older rifles still being used.

There is no flaw when the loading data for the 6.5x55 Swedish Mauser is for the older Krag and Mauser actions and the newer actions can take more pressure.

And there is no flaw in the standard of measuring the case expansion just above the extractor groove for high pressure.

And all reload data is ballpark information because of the wide variations in firearms and components and "WHY" you make workup loads.

Below is a brass hardness test by my buddy Catshooter, the Remington case will show base expansion long before the Lake City case with much harder brass in the base. Catshooter later posted the results of Federal brass that was the softest tested.

And you need to catch up on your reading, they have tested brass since the 1950s

The only flaw here is you stroking your ego and thinking your the only one who knows how to reload or check the case for signs of over pressure.


Have a nice day...... and get a life dude.
