Both of my grandfathers owned .270’s!
One was a Mauser custom, the other a stock Remington 721.
The Remington was the biggest (caliber wise) rifle that grandfather ever owned. To my knowledge he never shot anything heavier than 130 grain bullets for use on our mule deer, elk and black bear, along with the occasional coyote or pronghorn antelope.
The Mauser played second fiddle to that Grampa’s .30-06 which incidentally was also a Remington 721.
I myself inherited a Browning BBR in .270 some years back. With it I have taken coyotes and one cow elk, following the grandfatherly advice of preferring 130 grain bullets. I plan on using it for mule deer as soon as I can draw a good tag and take proper time to hunt.
Although a dyed-in-the-wool .30-06 man, I do appreciate the .270 for its many good attributes greatest of which is, it’s a darn good cartridge!
