Quick Answer
A 25-yard zero may be sufficient for long-range coyote hunting, but it depends on the terrain, wind conditions, and type of ammunition used. A 25-yard zero typically has a trajectory drop-off at around 300-400 yards, which may not be a concern for coyote hunting but could impact long-range hunting. However, it can be a good starting point.
Understanding the Ballistics of a 25-yard Zero
A 25-yard zero is a common starting point for hunting rifles, especially those chambered in calibers like .223 Remington or .308 Winchester. This zero point is typically set between 25 and 30 yards, depending on the rifle’s sight height and the type of ammunition used. At this zero point, the bullet is expected to drop around 1-2 inches at 100 yards, which is relatively flat.
Choosing the Right Ammunition for Long-range Hunting
When hunting coyotes at longer ranges, it’s essential to choose ammunition that can maintain its accuracy and trajectory. Look for ammunition with a ballistic coefficient (BC) of 0.4 or higher, which indicates a more aerodynamic bullet. For example, some popular long-range coyote hunting ammunition includes the Sierra MatchKing 55-grain .223 Remington (BC: 0.45) or the Hornady 168-grain .308 Winchester (BC: 0.485). These bullets are designed to maintain their velocity and trajectory at longer ranges.
Considerations for Long-range Coyote Hunting
When hunting coyotes at longer ranges, it’s essential to consider the terrain and wind conditions. Flat, open terrain can make it easier to judge distances, but wind can quickly affect the bullet’s trajectory. Use a rangefinder or a ballistic calculator to determine the correct holdover or wind deflection. Additionally, consider using a scope with a high power range (e.g., 10x or 12x) to help with long-range shots.
