Best ammo types for .243 when hunting in cold climates?

Cold-Weather Performance

When hunting in cold climates, it’s essential to choose ammunition that can maintain its velocity and retain its expansion characteristics at lower temperatures. A higher BC bullet is crucial in this scenario as it will retain its aerodynamic shape and continue to fly true, even in sub-zero temperatures. Look for bullets with a BC of 0.4 or higher, such as the Hornady ELD-X or Berger VLD. These bullets will provide a flatter trajectory and better accuracy in cold weather.

Bullet Weight and Expansion

In cold climates, it’s also essential to choose a heavier bullet, typically in the range of 90-105 grains. Heavier bullets penetrate deeper and expand more consistently, even in denser tissues like deer meat. This is especially important in cold weather, where deer tend to have thicker coats and a higher body fat percentage. A bullet with a weight of 95-100 grains, such as the Winchester Power Point or Federal Premium, is a good choice for hunting in cold climates.

Real-World Testing and Recommendations

In real-world testing, ammunition such as the 90-grain Hornady V-Max and the 95-grain Winchester Power Point have shown reliable performance in cold temperatures. These bullets penetrate deep and expand consistently, providing a quick and humane kill. When choosing ammo for hunting in cold climates, prioritize bullets with a high BC and a heavier weight. This will ensure that you have the best chance of a successful and humane harvest, even in the most challenging weather conditions.
