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 slugs from 100 to 150 grains, it joins level direction with moderate force. Speeds can finish off 3,000 fps with a 140-grain projectile without stretching boundaries, and since the cartridge appeared during the 1920s, it has consistently stayed a generally well known bullet.
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 rivalry cartridge by plan – mating long, high-BC wind-kicking slugs with a short, proficient case and low backlash – the 6.5 380 acp ammo 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 projectiles from 95 to 160 grains, the .270 with shots from 100 to 150 grains, so there are more choices with the 6.5.
Yet, the .270 Win. enjoys a benefit regarding sheer speed and energy. With a 140-grain shot, the 6.5 Creedmoor battles to arrive at 2,725 fps, while 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 drawn out activity, and the outcome is a heavier firearm that creates more backlash.
However, gag speed is just a single part of a cartridge that can perform at longer ranges. You should likewise think about a shot’s ballistic coefficient, and the 6.5 Creedmoor has the high ground there. The 129-grain Hornady InterBond 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 surpasses the 140-grain .270.
SST’s figure of .495. That likens to less wind float, and the long, weighty 6.5
slug’s high sectional thickness implies a Greedmoor shot implied for hunting will enter profound to drop major game. The Creedmoor is likewise a stunningly productive cartridge plan. With 140-grain slugs 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, thusly, to reload the Creedmoor, with regards to powder utilization. What’s more, albeit the .270 Win. is barely to be viewed as a weighty drawing back round, it produces around 15% more force than the coy 6.5 Creedmoor, as well as more gag impact.
Practically every centerfire ammo maker offers somewhere around one burden for the .270 Win.; the equivalent can’t be said for the 6.5 Creedmoor-basically not yet. In like manner, basically every manual rifle made offers a .270 variation, in spite of the fact that makers like Savage and Browning are adding rifles loaded in 6.5 Creedmoor consistently.
In the event that the cartidge’s direction proceeds, it very well may be as broadly accessible in the future as the.270, however for the second the Winchester cartridge stays the more universal decision. As far as use on deer-size game, both of these cartridges will function admirably to longer ranges.
On bigger game like elk, the .270 Win. enjoys the benefit. Assuming you accept the maxim that it takes 2,000 ft.- lbs. of energy to kill a bull, then the .270 conveys that degree of energy with most loads to about 300 yards though the ordinary 6.5 Creedmoor load falls underneath that number somewhere in the range of 100 and 200 yards.
In the event that you don’t handload, the .270 is likely a superior choice basically in light of the fact that rifles and ammunition are all over. In the event that you handload, you can exploit the wide assortment of 6.5 shots. Main concern is that these two cartridges will work well for you, and hanging the expression “failure” on possibly one is unimaginable.”
Better execution at moderate reaches
Extended history on game
Immense ammunition, rifle choice
Requires longer activity, heavier rifle
Creates more backlash than the 6.5
Not as incredible part slug determination
Short-activity rifles and low backlash
Astounding BC and SD figures
Progressively more weapon, ammunition decisions
Not as viable on elk-size game
Ammunition still not broadly accessible
Future not cut in stone
