-
Wind
Wind can significantly deflect a projectile, especially at longer ranges. The .300 Blackout, like all cartridges, is susceptible to wind drift. Heavier bullets are generally less affected due to their higher momentum. Crosswinds exert the most influence, requiring shooters to compensate for drift. For instance, a 10 mph crosswind can deflect a .300 Blackout bullet several inches at 300 yards, potentially resulting in a missed shot. Understanding wind direction and velocity is critical for accurate long-range shooting.
-
Temperature
Temperature affects air density, influencing the projectile’s flight. Higher temperatures decrease air density, resulting in less resistance and slightly increased velocity. Conversely, lower temperatures increase air density, increasing drag and reducing velocity. While these effects might seem minimal, they become more pronounced at longer ranges. For example, a significant temperature difference between the shooting range and the intended hunting environment could impact point of impact, highlighting the importance of considering temperature variations.
-
Altitude
Altitude, similar to temperature, affects air density. Higher altitudes have lower air density, leading to reduced drag and increased projectile velocity. Conversely, lower altitudes with denser air increase drag and decrease velocity. Shooters transitioning between significantly different altitudes may need to adjust their aiming points to compensate for these variations in ballistic performance. Understanding the impact of altitude on trajectory is particularly important for long-range shooting in mountainous terrain.
-
Humidity
Humidity, though less influential than wind, temperature, or altitude, can subtly affect ballistic performance. Higher humidity slightly increases air density, marginally increasing drag.
