Cartridge Clash – .270 Win Vs 6.5 Greedmoor
The .270 Win. has accomplished worldwide acknowledgment by athlete because of its gentle attitude and deadly potential. With projectiles from 100 to 150 grains, it consolidates level direction with moderate force. Speeds can finish off 3,000 fps with a 140-grain slug without stretching boundaries, and since the cartridge appeared during the 1920s, it has consistently stayed a somewhat famous round.
In 2007, Hornady’s Dave Emary and champion shooter Dennis Demille planned a 6.5 rivalry cartridge in light of the .30 T/C. In contrast to its parent cartridge, the 6.5 Creedmoor won fans in a rush. While it was a 10mm ammo for salecartridge by plan – mating long, high-BC wind-kicking shots with a short, productive case and low force – the 6.5 Creedmoor immediately turned into a hybrid round.
There’s a lot of cross-over between the .270 and 6.5 in the field. The Creedmoor utilizes slugs from 95 to 160 grains, the .270 with projectiles from 100 to 150 grains, so there are more choices with the 6.5.
Be that as it may, the .270 Win. enjoys a benefit concerning sheer speed and energy. With a 140-grain slug, the 6.5 Creedmoor battles to arrive at 2,725 fps, though the .270 Win. can undoubtedly top 2,900 fps and could in fact break 3,000. Yet, the additional speed and energy requires more powder, a more extended activity, and the outcome is a heavier weapon that produces more force.
However, gag speed is just a single part of a cartridge that can perform at longer ranges. You should likewise think about a projectile’s ballistic coefficient, and the 6.5 Creedmoor has the high ground there. The 129-grain HornadyInterBond 6.5 projectile has a BC of .485 contrasted with the 130-grain .270 Inter-Bond’s .460; the 140-grain 6.5 SST’s.520 BC eclipses the 140-grain .270.
SST’s figure of .495. That compares to less wind float, and the long, weighty 6.5
projectile’s high sectional thickness implies a Greedmoor shot implied for hunting will infiltrate profound to drop major game. The Creedmoor is likewise a magnificently effective cartridge plan. With 140-grain shots the 6.5 Creedmoor accomplishes 2,700 fps with 42.3 grains of Hybrid 100V powder or 42.8 grains of Winchester 760.
To accomplish that equivalent speed with a .270, you’ll require 49.2 and 50.3 grains of powder, individually. It’s more affordable, accordingly, to reload the Creedmoor, with regards to powder utilization. Also, albeit the .270 Win. is barely to be viewed as a weighty pulling back round, it produces around 15% more force than the bashful 6.5 Creedmoor, as well as more gag impact.
