Quick Answer
Altitude affects .308 performance on elk by increasing the bullet's trajectory, making it drop farther and faster due to the thinner air. This can lead to longer shots and increased bullet expansion.
Ballistic Considerations
When hunting at high elevations, it’s essential to consider the ballistic effects of altitude. For every 1,000 feet of elevation gain, the effective range of a .308 Winchester cartridge decreases by about 100-150 yards. This is due to the reduced air density, which causes the bullet to lose velocity and drop more. For example, at 7,000 feet elevation, a .308 Winchester 150-grain bullet might experience a 300-yard decrease in effective range.
Practical Implications for Elk Hunting
To compensate for the increased bullet drop, hunters may need to adjust their shots by aiming higher than normal. However, this can be challenging, especially when shooting from a distance or in windy conditions. A practical approach is to use a ballistic calculator or consult a ballistics chart for the specific cartridge and bullet being used. This can help determine the adjusted point of impact at various distances and elevations. Additionally, selecting a cartridge with a flatter trajectory, such as a .30-06 Springfield or a .300 Winchester Magnum, can be beneficial when hunting at high elevations.
Hunting at High Elevation
When hunting elk at high elevations, it’s crucial to understand the effects of altitude on bullet performance. This knowledge can help hunters make more accurate shots and increase their chances of success. By considering the ballistic effects of altitude and adjusting their shots accordingly, hunters can effectively adapt to the unique conditions of high-elevation hunting.
