Quick Answer
The 150gr and 165gr loads exhibit noticeable differences in performance, particularly when it comes to velocity, expansion, and penetration. However, the magnitude of these differences may not significantly impact the hunter's effectiveness in the field.
Velocity Comparison
When comparing the 150gr and 165gr loads in the 308 Winchester, the 150gr load typically achieves a higher muzzle velocity, around 2,900-3,000 feet per second (fps), while the 165gr load clocks in at 2,800-2,900 fps. This 100-200 fps difference may not seem substantial, but it can affect the bullet’s kinetic energy and potential for penetration.
Expansion and Penetration
In terms of expansion and penetration, the 165gr load often exhibits a more consistent and deeper penetration due to its heavier weight and slightly larger diameter. For example, the Remington 165gr Core-Lokt load expands to approximately 0.55-0.65 inches, while the Hornady 150gr SST load expands to around 0.40-0.55 inches. However, both loads can effectively anchor deer with proper shot placement.
Real-World Implications
In a real-world hunting scenario, the differences between the 150gr and 165gr loads may be less pronounced than expected. Both loads can be effective for deer hunting, and the choice ultimately comes down to personal preference and specific hunting conditions. If you’re hunting larger game or need a deeper penetration, the 165gr load may be a better choice. However, if you’re hunting smaller game or prefer a faster, flatter-shooting load, the 150gr load could be a better option.
