Straight-walled cartridges have surged in popularity, particularly for hunting within specific regulations and for their suitability in various shooting disciplines. This comprehensive guide delves into a list of straight-walled rifles, examining their features, applications, and suitability for different needs. We'll explore the advantages and disadvantages of straight-walled cartridges and help you determine which rifle is right for you.
Understanding Straight-Walled Cartridges
Straight-walled cartridges, unlike bottlenecked cartridges, feature a case that is essentially cylindrical from the base to the shoulder. This design offers several key advantages:
- Improved Feeding Reliability: The straight wall design promotes smoother feeding in semi-automatic and lever-action rifles, minimizing malfunctions.
- Greater Case Capacity (Sometimes): Compared to some bottlenecked cartridges of similar length, straight-walled designs can sometimes offer slightly higher powder capacity, leading to increased velocity or heavier bullet weights.
- Simpler Manufacturing: The simpler design generally translates to lower manufacturing costs for both ammunition and firearms.
However, there are also some drawbacks:
- Lower Ballistic Efficiency (Generally): Straight-walled cartridges generally don't achieve the same ballistic efficiency (velocity and long-range accuracy) as bottlenecked cartridges of the same caliber due to less efficient powder burn.
- Limited Long-Range Performance: The shorter, straighter case often results in less aerodynamic bullets, impacting long-range accuracy.
- Regulations: The popularity of straight-walled rifles is partly due to hunting regulations in some states that restrict the use of bottlenecked cartridges.

- Disadvantages: Heavy recoil, significantly higher ammunition cost.
5. 350 Legend
- History: A relatively newer straight-walled cartridge gaining popularity.
- Applications: Designed for deer hunting within specific state regulations.
- Rifle Choices: Many AR-15 platform rifles are chambered for the 350 Legend.
- Advantages: Moderate recoil, good accuracy, relatively affordable ammunition.
- Disadvantages: A relatively newer cartridge, with a smaller selection of ammunition compared to some other calibers.
Choosing the Right Straight-Walled Rifle
Selecting the best straight-walled rifle depends heavily on your intended use:
| Criterion | .45-70 Gov't | .44 Magnum | .450 Bushmaster | 458 SOCOM | 350 Legend |
|---|---|---|---|---|---|
| Game Size | Large | Medium | Medium-Large | Large | Medium |
| Range | Short | Short-Med | Short-Med | Short | Short-Med |
| Recoil | High | Moderate | Moderate | High | Moderate |
| Ammunition Cost | Low | Low | Moderate | High | Low-Moderate |
| Rifle Availability | High | High | High | High | High |
This table provides a general comparison. Always consult the specifications of the specific rifle and cartridge before purchase.
Conclusion
Straight-walled rifles offer a compelling choice for hunters and shooters, particularly where regulations restrict bottlenecked cartridges or where the advantages of the design outweigh limitations. Careful consideration of the caliber's intended application, recoil characteristics, ammunition availability, and the rifle's overall features is crucial for making an informed decision. Remember to always prioritize safety and handle firearms responsibly.
