Does bullet construction influence terminal performance of .325 WSM on elk?

Bullet Design Considerations

When selecting a .325 WSM bullet for elk hunting, it’s essential to consider the bullet’s design, particularly its expansion characteristics. For example, a controlled-expansion bullet like the Hornady InterLock or the Remington Core-Lokt may expand consistently, retaining a significant portion of its weight and causing deep penetration. In contrast, a monolithic bullet like the Nosler AccuBond or the Barnes TSX may maintain its ballistic integrity but may not expand as significantly, potentially resulting in shallower penetration.

Penetration and Expansion Data

To illustrate the differences in terminal performance, consider the following data: the Hornady 180-grain InterLock expands to approximately 0.65 inches in diameter at 1,000 yards, while the Nosler 180-grain AccuBond expands to around 0.45 inches. Meanwhile, the Barnes 180-grain TSX maintains its ballistic shape, with minimal expansion. In terms of penetration, the Hornady InterLock achieves an average of 24 inches in gelatin, while the Nosler AccuBond reaches approximately 18 inches. These differences in expansion and penetration can significantly impact the effectiveness of the bullet in taking down elk.

Real-World Testing and Recommendations

In real-world testing, the .325 WSM has proven to be an effective cartridge for elk hunting, with numerous successful shots taken at various ranges. However, to achieve optimal results, it’s crucial to select the right bullet for the job. Based on the data and design considerations mentioned above, I recommend using a controlled-expansion bullet like the Hornady InterLock or the Remington Core-Lokt for elk hunting. These bullets have consistently demonstrated reliable expansion and deep penetration, making them well-suited for taking down large game like elk.
