All about the common usage of a word or phrase. "Calibre" being a perfect example in the world of guns. Just about every time the word Calibre is used what is really meant is Cartridge.

Look here https://weatherby.com/store/markv-accumark/ Scroll down and there is a drop down list headed Calibre.

Actually even "bore size" in common use is bullet diameter. In common usage when "big" is added to "bore" it means power and/or case capacity. If Winchester was to chamber for the 375/06 you can bet it would not be in the same rifles as they chamber for the 375, 416 and 458
