Quick Answer
The 6.5x55mm Swedish cartridge performs well in cold weather, offering a relatively flat trajectory and decent velocity retention at low temperatures. It's a popular choice for hunting large game, including moose, in Scandinavian countries. However, it requires precise shot placement and a reliable rifle.
Ballistic Performance in Cold Weather
The 6.5x55mm cartridge’s ballistic performance is influenced by temperature, with lower temperatures resulting in a slightly flatter trajectory due to the reduced air density. At 32°F (0°C), the 6.5x55mm’s velocity retention is around 85-90% of its initial velocity, whereas at -20°F (-29°C), it retains around 75-80% of its initial velocity. This means that the cartridge will still maintain a relatively flat trajectory, but with some velocity loss.
Hunting Large Game in Cold Weather
When hunting large game like moose in cold weather, the 6.5x55mm cartridge’s accuracy and penetration capabilities are essential. To maximize its performance, it’s crucial to use a high-quality bullet with a robust design, such as the 140-grain or 150-grain projectile. Additionally, shooting from a rest and using a rifle with a heavy barrel can help mitigate the effects of cold weather on the cartridge’s performance. Aiming for the vitals, particularly the heart-lung area, is also critical for a quick and humane kill.
