Choosing the right cartridge for your hunting or long-range shooting needs can be a daunting task. Two popular choices often compared are the .243 Winchester and the .243 Winchester Super Short Magnum (WSSM). While both use the same projectile diameter, their performance characteristics differ significantly. This article will dissect the key differences between the .243 WSSM and the .243 Winchester to help you make an informed decision.
Ballistics: A Key Differentiator
The most significant difference between the two cartridges lies in their ballistics. The .243 WSSM boasts a higher velocity and flatter trajectory due to its shorter, fatter case design and higher pressure. This translates to longer effective range and increased energy at longer distances. However, this higher velocity comes at a cost.
Velocity and Energy
-
.243 Winchester: Typically achieves velocities around 2800-3200 fps (feet per second) depending on the powder and bullet weight. Energy levels are respectable for medium-sized game but decrease significantly at longer ranges.
-
.243 WSSM: Delivers substantially higher velocities, often exceeding 3400 fps, again depending on the load. This higher velocity results in significantly more retained energy downrange.
Trajectory
The .243 WSSM's higher velocity leads to a flatter trajectory. This means less bullet drop at extended ranges, making long-range shots more predictable and accurate. The .243 Winchester, while accurate, experiences more significant bullet drop at longer distances, requiring more precise aiming adjustments.
Recoil and Felt Recoil
The increased power of the .243 WSSM also results in higher recoil. While experienced shooters might not find this problematic, beginners or those sensitive to recoil might prefer the gentler recoil of the .243 Winchester. The difference in recoil is noticeable and should be considered.
Rifle Availability and Cost
Finding rifles chambered in .243 Winchester is significantly easier and often more cost-effective than finding .243 WSSM rifles. The popularity and widespread adoption of the .243 Winchester mean a larger selection of rifles, manufacturers, and price points are available. The .243 WSSM, having a smaller market share, offers fewer choices.
Ammunition Availability and Cost
Similarly, ammunition for the .243 Winchester is readily available at most sporting goods stores and online retailers. The .243 WSSM ammunition is less common and can be more expensive. This can be a significant factor to consider, particularly for those who shoot frequently.
Applications: Hunting and Long-Range Shooting
Both cartridges are suitable for various hunting applications, particularly for medium-sized game like deer and antelope. However, the .243 WSSM's superior ballistics give it an edge at longer ranges. For long-range shooting enthusiasts, the flatter trajectory and increased energy of the .243 WSSM are highly advantageous. The .243 Winchester remains a great choice for hunters prioritizing a less powerful, more manageable round.
Conclusion: Choosing the Right Cartridge
The decision between the .243 WSSM and the .243 Winchester depends entirely on your priorities and shooting style. The .243 Winchester is a proven performer, ideal for hunters who value ease of use, readily available ammunition, and lower recoil. The .243 WSSM, on the other hand, excels at long-range shooting and delivers superior ballistics, though at the cost of increased recoil, ammunition availability, and rifle selection. Carefully consider your needs before making your choice.
