Cartridge Clash – .270 Win Vs 6.5 Greedmoor

The. 270 Win. It has achieved worldwide acceptance by athletes thanks to its mild demeanor and lethal potential. With 100-150 grain bullets, it combines flat trajectory with moderate recoil. Speeds can exceed 3,000 fps with a 140-grain bullet without pushing the limits, and since the cartridge debuted in the 1920s, it has always been a relatively popular hunting cartridge.

In 2007, Dave Emary of Hornady and champion marksman Dennis Demille designed a 6.5 competition cartridge based on the .30 T / C. Unlike its main cartridge, the 6.5 Creedmoor quickly gained fans. While it was a competition cartridge by design, combining long, high BC wind resistant bullets with an efficient short casing and low recoil, the Creedmoor 6.5 quickly became a cross-over hunting cartridge.

There’s a big overlap between .270 and 6.5 on the field. The Creedmoor uses 95 to 160 grain bullets, the .270 with 100 to 150 grain bullets, so there are more options with the 6.5.

But. 270 Win. it has an advantage in terms of sheer speed and energy. With a 140-grain bullet, the 6.5 Creedmoor struggles to hit 2725 fps, while the .270 Win. it can easily exceed 2900 fps and even exceed 3000. But the extra speed and energy require more gunpowder, longer action, and the result is a heavier weapon that generates more recoil.

However, muzzle velocity is only one aspect of a cartridge that can perform at longer ranges. You also have to consider the ballistic coefficient of a bullet, and the Creedmoor 6.5 has the advantage there. The 129-grain Hornady InterBond 6.5 bullet has a BC of .485 compared to the .270 130-grain Inter-Bond bullet .460; the 140 grain 6.5 SST’s. 520 BC outshines the 140-grain one. 270.

SST figure of .495. That equates to less wind drift, and the long and heavy 6.5

The bullet’s high sectional density means that a Greedmoor bullet intended for hunting will penetrate deep to drop big game. The Creedmoor is also a masterfully efficient cartridge design. With 140-grain bullets, the 6.5 Creedmoor hits 2700 fps with 42.3 grains of 100V hybrid powder or 42.8 grains of Winchester 760.

To achieve the same speed with a .270, you will need 49.2 and 50.3 grains of powder, respectively. So it’s less expensive to recharge the Creedmoor, at least in terms of dust consumption. And although the. 270 Win. It can hardly be considered a heavy recoil ammo, generating around 15 percent more recoil than the demure 6.5 Creedmoor, as well as more muzzle blast.

Virtually all centerfire ammunition manufacturers offer at least one charge for the .270 Win .; The same can’t be said for the 6.5 Creedmoor, at least not yet. Likewise, virtually every bolt-action rifle manufactured offers a .270 variant, although manufacturers such as Savage and Browning are adding rifles chambered in 6.5 Creedmoor every year.

If the cartridge trajectory continues, it could be as widely available in the future as the 270, but for now the Winchester cartridge remains the most ubiquitous option. In terms of use on deer-sized game animals, both cartridges will work perfectly well at longer ranges.

In bigger games like Moose, the .270 Win. has the advantage. If you believe the adage that it takes 2,000 foot-pounds. of energy to kill a bull, so the .270 brings that energy level with most charges to about 300 yards, while the typical 6.5 Creedmoor charge falls below that number by between 100 and 200 yards.

If you don’t load manually, the .270 is probably a better option simply because rifles and ammunition are everywhere. If you load manually, you can take advantage of the wide variety of 6.5 bullets. The bottom line is that these two cartridges will serve you well, and it’s impossible to hang the term “loser” on either one.
