The .270 Win. has achieved world acceptance by sportsman because of its gentle demeanor and deadly potential. With bullets from 100 to 150 grains, it combines flat trajectory with reasonable recoil. Velocities can high three,000 fps with a 140-grain bullet with out pushing limits, and for the reason that cartridge debuted within the 1920s, it has at all times remained a comparatively well-liked searching cartridge.
In 2007, Hornady’s Dave Emary and champion shooter Dennis Demille designed a 6.5 competitors cartridge based mostly on the .30 T/C. In contrast to its guardian cartridge, the 6.5 Creedmoor gained followers in a rush. Whereas it was a contest cartridge by design – mating lengthy, high-BC wind-bucking bullets with a brief, environment friendly case and low recoil – the 6.5 Creedmoor shortly grew to become a crossover searching cartridge.
There’s quite a lot of overlap between the .270 and 6.5 within the area. The Creedmoor makes use of bullets from 95 to 160 grains, the .270 with bullets from 100 to 150 grains, so there are extra choices with the 6.5.
However the .270 Win. has a bonus by way of sheer velocity and power. With a 140-grain bullet, the 6.5 Creedmoor struggles to succeed in 2,725 fps, whereas the .270 Win. can simply high 2,900 fps and might even break three,000. However the additional velocity and power requires extra powder, an extended motion, and the result’s a heavier gun that generates extra recoil.
Muzzle velocity is just one facet of a cartridge that may carry out at longer ranges, although. You need to additionally contemplate a bullet’s ballistic coefficient, and the 6.5 Creedmoor has the higher hand there. The 129-grain Hornady InterBond 6.5 bullet has a BC of .485 in comparison with the 130-grain .270 Inter-Bond’s .460; the 140-grain 6.5 SST’s.520 BC outshines the 140-grain .270.
SST’s determine of .495. That equates to much less wind drift, and the lengthy, heavy 6.5
bullet’s excessive sectional density means a Greedmoor bullet meant for searching will penetrate deep to drop large recreation. The Creedmoor can be a masterfully environment friendly cartridge design. With 140-grain bullets the 6.5 Creedmoor achieves 2,700 fps with 42.three grains of Hybrid 100V powder or 42.eight grains of Winchester 760.
To realize that very same velocity with a .270, you will want 49.2 and 50.three grains of powder, respectively. It is inexpensive, due to this fact, to reload the Creedmoor, no less than by way of powder consumption. And though the .270 Win. is hardly to be thought of a heavy-recoiling spherical, it generates about 15 % extra recoil than the demure 6.5 Creedmoor, in addition to extra muzzle blast.
Nearly each centerfire ammunition producer provides no less than one load for the .270 Win.; the identical cannot be mentioned for the 6.5 Creedmoor-at least not but. Likewise, just about each bolt-action rifle made provides a .270 variant, though producers like Savage and Browning are including rifles chambered in 6.5 Creedmoor yearly.
If the cartidge’s trajectory continues, it may very well be as extensively out there sooner or later because the.270, however for the second the Winchester cartridge stays the extra ubiquitous alternative. By way of use on deer-size recreation, each of those cartridges will work completely properly to longer ranges.
On bigger recreation like elk, the .270 Win. has the benefit. When you imagine the adage that it takes 2,000 ft.-lbs. of power to kill a bull, then the .270 carries that degree of power with most hundreds to roughly 300 yards whereas the standard 6.5 Creedmoor load falls under that quantity between 100 and 200 yards.
When you do not handload, the .270 might be a greater possibility just because rifles and 30-30 ammo 500 rounds are all over the place. When you handload, you’ll be able to benefit from the wide range of 6.5 bullets. Backside line is that these two cartridges will serve you properly, and it is not possible to hold the time period “loser” on both one.
