The .270 Winchester remains a popular choice among hunters and target shooters for its versatility, accuracy, and impressive ballistics. Understanding its ballistic performance is crucial for making informed decisions regarding ammunition selection and shot placement. This guide provides a comprehensive .270 Winchester ballistics table, along with explanations to help you interpret the data and choose the right cartridge for your needs. Note that the data presented here is for general informational purposes and may vary based on several factors, including barrel length, altitude, temperature, and the specific ammunition manufacturer. Always refer to the manufacturer's specifications for the most accurate information.
Understanding Ballistic Data
Before diving into the table, let's define the key terms:
- Bullet Weight (grains): The weight of the projectile, typically expressed in grains. Heavier bullets generally have flatter trajectories but lower velocities.
- Muzzle Velocity (fps): The speed of the bullet as it leaves the barrel, measured in feet per second. Higher velocity generally translates to longer range and flatter trajectory.
- Muzzle Energy (ft-lbs): The kinetic energy of the bullet as it leaves the barrel, measured in foot-pounds. Higher energy indicates greater stopping power.
- Trajectory (inches): The bullet's vertical drop from the line of sight at various ranges. A flatter trajectory means less compensation is needed for long-range shots.
- Velocity at Range (fps): The speed of the bullet at specified distances downrange.
- Energy at Range (ft-lbs): The kinetic energy of the bullet at specified ranges.
270 Winchester Ballistics Table (Example Data)
The following table represents example ballistic data for a 130-grain .270 Winchester bullet fired from a 24-inch barrel. Actual results may vary. This is NOT an exhaustive table and should not replace data from your specific ammunition manufacturer.
| Distance (yards) | Velocity (fps) | Energy (ft-lbs) | Trajectory (inches) |
|---|---|---|---|
| 0 (Muzzle) | 3000 | 2850 | 0 |
| 100 | 2750 | 2300 | -1 |
| 200 | 2500 | 1800 | -4 |
| 300 | 2280 | 1400 | -9 |
| 400 | 2050 | 1050 | -16 |
| 500 | 1850 | 750 | -25 |
Disclaimer: This is sample data. Actual ballistic performance will vary depending on several factors including ammunition manufacturer, barrel length, atmospheric conditions, and the specific bullet used. Consult your ammunition manufacturer's data for precise figures.
Factors Affecting Ballistics
Several factors can significantly impact the ballistic performance of the .270 Winchester:
- Barrel Length: Longer barrels generally produce higher velocities.
- Ammunition Manufacturer: Different manufacturers produce ammunition with varying ballistic characteristics.
- Bullet Design: The bullet's shape, weight, and construction affect its trajectory, energy retention, and overall performance.
- Altitude and Temperature: Higher altitudes and lower temperatures can reduce bullet velocity.
- Wind: Wind significantly impacts bullet trajectory, especially at longer ranges.
Choosing the Right Ammunition
Selecting the appropriate .270 Winchester ammunition depends on your intended use. For hunting larger game at longer ranges, heavier bullets with higher ballistic coefficients are often preferred for better energy retention. For smaller game or target shooting at shorter ranges, lighter bullets may suffice.
Always carefully consider your target, the environment, and your skill level when selecting ammunition. Safe and responsible firearm handling practices are paramount. This information is for educational purposes only and should not be considered a substitute for professional training or advice.
