Acting like fools? Well, if the best response you can formulate to posting misleading information here is to call names, then it ought to be pretty apparent who the real fool here is.

It remains - Your assertion that the metric designation brought out with the cartridge in 1957 is patently false. It's very clear that the metric designation did not arrive until 1979, well after the .270 had won the popularity contest between it and the .280.

And while Jack O'Connor was a fine writer, and while he did extol the virtues of the .270, your further cites don't change the fact that your initial explanation here was off the mark.

I think we're done here.
