Quick Answer
Temperature can significantly impact crossbow performance and bolt selection. As temperature fluctuates, crossbow accuracy, kinetic energy, and bolt flight stability are affected. Hunters must consider these factors when selecting the right crossbow and bolt for the conditions.
Bolt Performance by Temperature
Bolt performance is highly dependent on temperature. As temperature increases, kinetic energy decreases. For example, a 120-pound crossbow bolt traveling at 300 feet per second at 60°F (15°C) will slow down to 260 feet per second at 90°F (32°C). This reduction in velocity affects the bolt’s effective range. At 90°F, a 120-pound bolt will have a reduced effective range of 40 yards, whereas at 60°F, it can reach 50 yards.
Crossbow Selection Based on Temperature
When selecting a crossbow, consider the temperature range you will be hunting in. For colder temperatures, look for a crossbow with a higher kinetic energy rating, typically above 120 foot-pounds. In warmer temperatures, a lower kinetic energy rating may be sufficient. Additionally, consider the cocking device. A rope cocking system is more effective in cold temperatures, as the rope maintains its elasticity better than a stirrup cocking system.
Broadhead Selection for Temperature Fluctuations
Broadhead selection is also influenced by temperature. In warmer temperatures, a broadhead with a higher BC (ballistic coefficient) is preferred, as it will maintain its accuracy and penetration. In colder temperatures, a broadhead with a thicker blade and more aggressive cutting edge is more effective, as it will maintain its penetration power in denser air. Always check local regulations for broadhead restrictions and ensure compliance.
