Quick Answer
Altitude can significantly affect .338 Federal performance for elk, with bullet energy loss increasing by 15-20% at 9,000 feet and 30-40% at 12,000 feet due to lower air density. This loss is mainly attributed to the bullet's kinetic energy and aerodynamic characteristics.
Understanding the Effects of Altitude on .338 Federal
When hunting elk at high altitudes, it’s crucial to consider the effects of air density on bullet performance. At 9,000 feet, the air density is approximately 75% of its sea-level value, causing a noticeable decrease in bullet energy. The .338 Federal, with its 210-grain bullet, will lose around 15-20% of its kinetic energy at this altitude.
Choosing the Right Ammunition for High-Altitude Hunting
To minimize the effects of altitude on .338 Federal performance, hunters can opt for ammunition with a heavier bullet, such as the 225-grain or 250-grain option. These heavier bullets will maintain more energy at high altitudes due to their greater mass and aerodynamic characteristics. For example, the 225-grain bullet will retain around 90% of its kinetic energy at 9,000 feet compared to the 210-grain bullet’s 80%.
Hunting Techniques and Altitude Considerations
When hunting elk at high altitudes, it’s essential to adjust hunting techniques to compensate for the reduced bullet performance. This can include using larger wound channels to ensure a quicker kill, and being prepared to make multiple shots if necessary. Additionally, hunters should consider the time of day and weather conditions, as these can also impact bullet performance.
