Quick Answer
The .338 Lapua Magnum and the 6.5 Creedmoor are top contenders for high-accuracy performance in high winds at distance, thanks to their flat trajectories and low wind drift.
Understanding the Challenges of High Winds
High winds pose a significant challenge to accuracy at distance, causing projectiles to deviate from their intended trajectory. The most effective calibers in these conditions are those with flat trajectories and low wind drift. The .338 Lapua Magnum, for example, has a ballistic coefficient (BC) of 0.73, which results in a relatively flat trajectory and minimal wind deflection. In contrast, the 6.5 Creedmoor boasts a BC of 0.57, making it an excellent choice for long-range shooting in windy conditions.
Choosing the Right Caliber
When selecting a caliber for high-accuracy performance in high winds, consider the following factors: muzzle velocity, BC, and bullet weight. The .338 Lapua Magnum, with its high muzzle velocity of 2,900 ft/s and heavy 300-grain bullets, provides excellent kinetic energy and penetration. The 6.5 Creedmoor, on the other hand, achieves a higher BC with lighter 140-grain bullets, resulting in a flatter trajectory and less wind deflection. Ultimately, the choice between these calibers depends on the specific needs of the shooter, including the intended range, wind conditions, and desired level of accuracy.
