It aims to combine the advantages of a short-action design with the long-range capabilities typically associated with larger, magnum cartridges. The intent was clear: to provide hunters and shooters with a cartridge that could deliver exceptional downrange energy and accuracy, even in challenging wind conditions.
Examining the Physical Attributes
The 270 Winchester utilizes a .277-inch diameter bullet, which is a very well-established bullet diameter, offering a broad selection of projectiles from a variety of manufacturers. Bullet weights commonly range from lighter, faster options for varmints and smaller game to heavier bullets suitable for larger ungulates. The 270 Winchester is known for its relatively flat trajectory.
The 6.8 Western uses the same .277-inch bullet diameter, ensuring compatibility with the same wide range of bullet types. However, a significant difference lies in the cartridge design, specifically its ability to accommodate longer, heavier bullets. This design allows the 6.8 Western to effectively launch heavier, more aerodynamic projectiles, which excel at retaining velocity and energy over longer distances. This is a key differentiating factor in its long-range performance.
The brass of the 270 Winchester tends to be slightly thinner compared to the 6.8 Western due to the pressures it’s typically designed to accommodate.
Performance on the Range: Trajectory, Energy, and Wind Drift
Trajectory is a critical factor in long-range shooting and hunting. A flatter trajectory means less bullet drop over distance, simplifying holdover adjustments. The 270 Winchester generally offers a flatter trajectory compared to many cartridges, making it relatively easy to shoot accurately at various distances.
The 6.8 Western, with its potential to launch high ballistic coefficient bullets at high velocities, offers a flatter trajectory than many in its class, especially when equipped with heavier bullets. Its superior ballistic coefficient means that its bullets resist wind drift more effectively and retain more energy downrange. This translates to increased accuracy and terminal performance at extended ranges.
Energy retention is crucial, especially when hunting. A cartridge with higher retained energy ensures more effective terminal performance, meaning the bullet delivers more impact and creates a wider wound channel. The 6.8 Western is designed to deliver significant downrange energy, thanks to its ability to propel heavier bullets at impressive velocities. This is a key advantage for hunters who need to consistently bring down large game at extended ranges.
Wind drift is the bane of long-range shooters and hunters. Wind affects a bullet’s path, and it’s crucial to account for this when calculating your shot. The 6.8 Western, with its high ballistic coefficient bullets, offers an advantage in this regard. Its bullets are less affected by wind, making it easier to compensate for wind conditions and improve accuracy. The 270 Winchester is subject to wind drift, but a keen shooter can account for it.
Terminal Performance and Hunting Applications: Where the Rubber Meets the Road
The ultimate test of a hunting cartridge is its ability to effectively harvest game. The 270 Winchester has a long history of success on a variety of big game animals, from deer to elk. Its flat trajectory and sufficient energy at reasonable ranges make it a versatile choice for many hunting scenarios. Bullet selection plays a significant role; choosing the right bullet type and weight for the intended game is paramount for achieving clean kills.
The 6.8 Western is designed to excel in hunting scenarios where long-range accuracy and energy delivery are critical. Its ability to launch heavier bullets with higher ballistic coefficients makes it a strong contender for large game at distances that were previously considered the domain of larger magnum cartridges. For hunters who prioritize downrange energy and resistance to wind drift, the 6.8 Western offers a compelling advantage.
Bullet selection is crucial with either cartridge. With the 270 Winchester, consider controlled-expansion bullets for tough game and those designed for the desired impact velocity. With the 6.8 Western, you’ll have a wider selection of heavier bullets optimized for long-range performance.
The suitability of these rounds depends on your hunting environment and game. The 270 Winchester works perfectly well in a wide variety of settings where shots aren’t too extreme. The 6.8 Western is at its best when dealing with long shots and heavy wind.
