That's right. In 1917, the 7mm Brenneke came out. It has a .284 bullet, 1:220mm (1:8.6") twist, and dimensions effectively identical to the -06 cartridge family - same case head diameter and an OAL a couple hundredths shorter. It fits in any gun that can be chambered in .30-06 or 8mm Mauser. Max pressure (CIP) is a reasonably modern 61KPSI giving it the same performance as a .280 Remington. In addition to all lighter bullet weights it's well suited to the 170+gr spire point hunting bullets suitable for elk sized game in this bore diameter.
Eight years later, Winchester introduced the completely inferior .270 with the wrong bore diameter, wrong twist, incapable of shooting good elk bullets, and with literally no advantages over the Brenneke other than familiarity. They were simply ignorant of what was going on in Europe and made an inferior cartridge that we're stuck with to this day.
