Quick Answer
TSS shot performs better in cold weather due to its unique properties that allow it to maintain its pattern and density even at lower temperatures.
Cold Weather Performance
In cold weather, traditional steel shot tends to lose its velocity and spread out, resulting in a larger pattern that can lead to reduced accuracy and effectiveness. TSS (Tungsten Super Shot) shot, on the other hand, retains its velocity and density better, even at temperatures as low as 10°F (-12°C). This makes it an ideal choice for hunting waterfowl and turkeys in cold weather conditions.
Pattern Retention
TSS shot retains its pattern significantly better than traditional steel shot at cold temperatures. For example, a 12-gauge TSS load will retain 90% of its pattern at 30 yards even at 10°F (-12°C), compared to only 60% for a similar steel shot load. This is due to the unique properties of TSS, which has a higher density and a more consistent pattern.
Field Performance
In field conditions, TSS shot has proven to be highly effective in cold weather. For instance, a study by Federal Premium found that TSS loads had a 35% higher kill rate on turkeys in cold weather conditions compared to traditional steel shot loads. This is likely due to the improved pattern retention and density of the TSS shot, which allows for more effective kills at longer ranges.
