Finn Aagaard. "the general purpose big-game cartridges used in this country come in but two calibers, 30 and 7mm (the .270 Win. is merely a slightly aberrant 7mm whose bullets are .007 undersize."
Actually, .270 is the true 7mm as that is the size of the bullets to one decimal place .277 = 7.0mm. Finn got his conversions wrong...no calculators back then
,257 The original statement was by Col. Townsend and it was the .30-06!!
Townsend Whelen's favorite cartridge was the .270 not the .30-06! He moved from the .30-06 to the .270.
"and there is no .277 equivalent of the 175gr .284 partition because it wouldn't stabilize in the slower twist .270." There's the 180 grain Woodleigh that will stabilise in a 10 twist barrel.
These are just a few of the mis-truths quoted by those individuals who for some ridiculous reason have a grudge against the excellent .270.
