Is using bonded bullets in sub-zero temperatures advisable?

Temperature and Bullet Expansion

When hunting in sub-zero temperatures, the primary concern with bonded bullets is their tendency to expand unevenly. This is because, in cold temperatures, the bullet’s core and jacket may not expand uniformly, resulting in a non-aerodynamic and unpredictable bullet flight. To minimize this risk, hunters can use bullets specifically designed for cold-weather hunting, such as the Hornady ELD-X, which has a unique heat-expansion core.

Penetration and Stopping Power

The uneven expansion of bonded bullets in cold temperatures can also compromise their penetration and stopping power. In extreme cases, the expanded bullet fragments may not be sufficient to quickly and humanely drop an elk. To address this concern, hunters can opt for bullets with a thicker jacket and a heavier weight, such as the 200-grain Nosler Partition, which provides greater penetration and a higher weight retention upon impact.

Field Experience and Performance

While bonded bullets can be effective in sub-zero temperatures, hunters should be prepared for the possibility of inconsistent performance. In the field, a hunter may need to adapt their shooting technique to compensate for the unpredictable bullet expansion. This may involve using a slower bullet that maintains its velocity and accuracy in cold temperatures, such as the 180-grain Barnes TSX, or switching to a different calibre altogether.
