The .270 Winchester and .270 Winchester Short Magnum (WSM) are both popular hunting cartridges known for their accuracy and effectiveness on a wide range of game. Choosing between them often comes down to specific hunting needs and personal preferences. This in-depth comparison will explore the key differences between the .270 WSM and .270 Winchester, helping you make an informed decision.
Ballistics: Power and Range
The most significant difference lies in their ballistic performance. The .270 WSM, being a short magnum, boasts considerably higher velocity and energy than its predecessor, the .270 Winchester.
Velocity and Energy
| Cartridge | Muzzle Velocity (fps) | Muzzle Energy (ft-lbs) |
|---|---|---|
| .270 Winchester | ~2900 | ~2500 |
| .270 WSM | ~3100 | ~3000 |
These figures are approximate and can vary based on bullet weight and specific ammunition.
As you can see, the .270 WSM delivers a noticeable increase in both muzzle velocity and energy. This translates to a flatter trajectory, meaning less bullet drop at longer ranges. This increased energy also results in greater penetration and stopping power, making it more effective on larger game.
Trajectory Comparison
The flatter trajectory of the .270 WSM is crucial for long-range shots. While the .270 Winchester is perfectly capable at moderate ranges, the .270 WSM maintains its accuracy and energy much further out. This is particularly beneficial in open country hunting scenarios. Imagine a 300-yard shot – the bullet drop difference between these two cartridges becomes significant, impacting accuracy and effectiveness. A ballistic calculator is a useful tool for comparing specific bullet trajectories based on your chosen ammunition.
Recoil: A Shooter's Consideration
The increased power of the .270 WSM comes at a cost – recoil. The .270 WSM kicks noticeably harder than the .270 Winchester. This is a critical factor for many hunters, particularly those who are less experienced or have sensitivities to recoil. The .270 Winchester's milder recoil makes it a more comfortable option for extended shooting sessions and for newer shooters.
Rifle Selection and Availability
The choice of cartridge also impacts the rifle selection. While many manufacturers produce rifles chambered in both cartridges, the .270 WSM is often associated with newer, more modern rifles designed for magnum cartridges. This sometimes means more expensive rifles or a limited selection compared to the widely available .270 Winchester rifles. Ammunition availability is generally good for both cartridges, but the .270 Winchester enjoys a slight edge due to its longer history and widespread popularity.
Hunting Applications: Choosing the Right Tool
Both cartridges excel as all-around hunting rounds, suitable for a wide range of game from deer to elk. However, their characteristics make them better suited for different situations:
-
.270 Winchester: Ideal for deer, antelope, and other medium-sized game at moderate ranges. Its manageable recoil makes it excellent for new hunters or those who prefer a lighter-recoiling cartridge.
-
.270 WSM: Better suited for larger game like elk and potentially more challenging long-range shots. Hunters who frequently shoot at longer distances or need increased penetration for tougher animals will appreciate its increased power.
Cost Considerations: Ammunition and Rifles
Generally, .270 WSM ammunition is slightly more expensive than .270 Winchester ammunition. This difference is relatively small but can accumulate over time, especially for hunters who shoot frequently. The rifles themselves often follow a similar pattern, with .270 WSM rifles generally being at a higher price point.
Conclusion: The Right Cartridge for You
The "better" cartridge depends entirely on the hunter's needs and preferences. The .270 Winchester offers a manageable recoil and excellent accuracy for most hunting situations involving medium-sized game. The .270 WSM, on the other hand, provides significantly increased velocity and energy, making it a superior choice for hunters needing to reach out farther, tackle larger game, or simply want the added power. Carefully consider your hunting style, preferred shooting distance, game you target, and recoil tolerance before making a decision. Both cartridges have proven themselves reliable and effective hunting rounds for decades.
