The .280 used to be called the 7mm express but was slow to be excepted, but the ballistics are far better from the .280 vs the .308, and as far as an Elk gun the .280 is by far the better choice. I think this is where we begin to make our biggest distinctions between the rounds. Additionally, the Browning X-Bolt, Kimber Hunter, Mossberg Patriot, Nosler Liberty, Ruger American, Ruger Hawkeye, Savage Axis, Thompson Center Compass, Tikka T3, and Weatherby Vanguard are available in both calibers.

Within a few decades, the .270 Winchester was firmly entrenched as one of the most popular hunting cartridges used in the United States. It is a well known cartridge, capable of travelling long distances with lots of energy to knock down your intended target. Also considered rebarreling one of my 270's to a 270x300 Win Mag.

The Lyman 50th Edition (197-198, p241-245), and Hornady 10th Edition (p251-355, p474-488) reloading manuals were also used as references for the history of the cartridges and provided data to compare their size and recoil. In summary, I had very good luck with my .308 downing elk and a couple bears but it’s too powerful for common deer at typical distances hunting the forests and foothills. Since both the 150gr loads have virtually the same muzzle velocity, the primary reason the .270 has more wind drift is because the .308 bullet has a significantly higher ballistic coefficient. I have done BC calculations on Hornady website and a .308 shoots just as flat and with more energy than a .270 when you get up to 150 and 160 gr bullets for the .270. The US Army began the search for a new rifle and cartridge after receiving a deadly demonstration of the capabilities of the revolutionary new Mauser rifle and 7mm Mauser cartridge in the hands of Spanish troops in Cuba during 1898.

But if you are looking for a hunting rifle or something that you can go shoot at targets at long range, both of these rounds would be excellent choices. Step up .013 inch and you have .277 inch, the bullet diameter of the .270 Winchester (and .270 WSM and Weatherby Magnum). As you can see, there is a significant difference in the bullet trajectories between the two cartridges. Still others consider the .270 worthless for elk hunting and recommend nothing less than a .300 Magnum as the absolute minimum elk cartridge. Both are also great for similarly sized game like black bear, feral hogs, javelina, mule deer, and pronghorn as well as exotic game like axis, sika, and fallow deer. These projectiles quite often take advantage of the latest developments in bullet development and offer advantages in precision and ballistic coefficient compared to the bullets used by the .270. My shots rarely exceeded 125 yards or so in the foothill country that I hunted in central Wyoming.
