7mm caliber, key word, caliber, is 0.284". The 280 Remington, aka 7mm Express, is.... 0.284". Some things you can not just simply google. A 30/30, 308, 30'06, 300 win mag, and 303 savage all use a 30 caliber bullet, that is.... 0.308". 325WSM, and 8mm Rem mag use a bullet, 0.323". A 270 WSM, 270 win, and a 270 wby, all shoot a bullet 0.277".
Now there was a gun that was 0.275" I believe, 275H&H.
