The .260 Remington, a popular cartridge known for its accuracy and versatility, has earned a dedicated following among hunters and long-range shooters. This ballistic table provides a detailed look at its performance, exploring various factors that influence bullet trajectory and energy. Understanding these nuances is crucial for making informed decisions about ammunition selection and shot placement. This analysis considers several bullet weights and velocities, providing a comprehensive overview for different applications.
Note: The data presented below is a representation based on average factory loads and conditions. Actual ballistics may vary based on several factors including barrel length, ammunition manufacturer, altitude, air temperature, and humidity. Always consult the ammunition manufacturer's data and your own chronograph testing for the most accurate information regarding your specific setup.
Understanding the Factors Affecting .260 Remington Ballistics
Before delving into the table, it's essential to understand the key factors influencing bullet performance:
-
Bullet Weight: Heavier bullets generally have lower velocities but maintain energy at longer ranges better due to their higher sectional density. Lighter bullets, conversely, have higher velocities but lose energy more rapidly.
-
Muzzle Velocity: This is the speed of the bullet as it leaves the barrel, significantly impacting trajectory and overall range. Higher muzzle velocity translates to flatter trajectories and longer ranges.
-
Ballistic Coefficient (BC): BC measures a bullet's ability to overcome air resistance. A higher BC means less energy loss over distance. Bullet shape and construction significantly influence its BC.
-
Twist Rate: The rifling twist rate of the barrel affects bullet stability. An improper twist rate can lead to inaccurate shots, particularly at longer ranges. The .260 Remington typically uses a 1:9" or 1:10" twist rate.
-
Environmental Conditions: Temperature, humidity, and altitude all affect air density, influencing bullet trajectory. Higher altitudes and colder temperatures mean less air resistance, resulting in flatter trajectories and extended range.
260 Remington Ballistics Table (Approximate Data)
This table provides estimated ballistic data for various .260 Remington loads. These are approximations based on commonly available factory ammunition. Consult your specific ammunition's packaging for precise data.
| Bullet Weight (grains) | Muzzle Velocity (fps) | Energy (ft-lbs) @ Muzzle | Range (yards) | Energy (ft-lbs) @ Range | Trajectory (inches) @ Range | BC |
|---|---|---|---|---|---|---|
| 120 | 2900 | 2100 | 300 | 1000 | -20 | 0.500 |
| 120 | 2900 | 2100 | 600 | 400 | -120 | 0.500 |
| 140 | 2700 | 2300 | 300 | 1200 | -15 | 0.550 |
| 140 | 2700 | 2300 | 600 | 600 | -80 | 0.550 |
| 160 | 2500 | 2400 | 300 | 1300 | -10 | 0.600 |
| 160 | 2500 | 2400 | 600 | 700 | -60 | 0.600 |
Note: Trajectory is measured at the given range, relative to the line of sight. Negative values indicate bullet drop below the line of sight.
Applications and Considerations
The .260 Remington's versatility makes it suitable for a variety of hunting and target shooting applications. Its moderate recoil and flatter trajectory make it an excellent choice for medium-to-large game hunting. Long-range precision shooting is also a common application, given its accuracy and manageable recoil.
Choosing the right ammunition depends on the specific application. Lighter bullets are suitable for varmints and shorter ranges, while heavier bullets excel at longer ranges and larger game. Proper bullet selection, combined with a thorough understanding of ballistics, is key to achieving consistent accuracy and ethical hunting practices.
Conclusion
The .260 Remington offers a potent combination of accuracy, range, and manageable recoil, making it a favored choice for both hunting and target shooting enthusiasts. By understanding the key factors impacting its ballistics and carefully selecting ammunition appropriate for the intended application, shooters can maximize the cartridge's potential for consistent accuracy and effective performance. Remember to always prioritize safety and consult your specific ammunition's data for the most accurate ballistic information.
