The .22-250 Remington is a popular choice among varmint hunters and long-range shooters, prized for its flat trajectory and impressive velocity. Understanding the ballistics of your chosen ammunition is crucial for accurate shot placement, especially at longer ranges. This article will delve into the ballistics of 55-grain projectiles in the .22-250 Remington, providing a comprehensive chart and insightful analysis to enhance your understanding and shooting performance. We'll explore factors influencing ballistics, offer tips for optimizing your load, and discuss the practical implications for hunting and target shooting.
Understanding Ballistics: Key Factors
Before diving into the specifics of a 55-grain .22-250 ballistic chart, let's clarify the key factors influencing projectile behavior:
-
Muzzle Velocity: This is the speed of the bullet as it leaves the barrel. Higher muzzle velocity generally translates to flatter trajectory and longer range. Variations in powder charge, barrel length, and ammunition manufacturer significantly impact muzzle velocity.
-
Ballistic Coefficient (BC): BC represents a bullet's ability to overcome air resistance. A higher BC means the bullet retains its velocity better over distance, leading to a flatter trajectory. The shape and weight of the bullet directly affect its BC. A 55-grain bullet will have a different BC depending on its design (e.g., boat-tail vs. flat-base).
-
Trajectory: This describes the bullet's path through the air. Factors like gravity, air resistance, and wind significantly influence trajectory. A flatter trajectory is desirable for longer-range shooting because it minimizes the required adjustments for elevation.
-
Energy: The kinetic energy of the bullet is determined by its weight and velocity. Sufficient energy is essential for effective hunting and target impact. Energy diminishes with distance due to air resistance.
-
Wind Drift: Wind significantly affects bullet trajectory, especially at longer ranges. Crosswinds push the bullet off course, requiring windage adjustments for accurate shot placement.

Disclaimer: The following data is a sample and represents typical performance. Actual ballistics can vary depending on the specific ammunition manufacturer, barrel length, altitude, temperature, and atmospheric conditions. Always refer to the manufacturer's data for your specific ammunition.
| Distance (yards) | Velocity (fps) | Energy (ft-lbs) | Drop (inches) | Wind Drift (10mph crosswind, inches) |
|---|---|---|---|---|
| 100 | 3500 | 1600 | 2 | 4 |
| 200 | 3100 | 1250 | 10 | 12 |
| 300 | 2750 | 950 | 25 | 24 |
| 400 | 2450 | 700 | 48 | 40 |
| 500 | 2150 | 500 | 80 | 60 |
Note: These figures are estimations and may not reflect the exact performance of every 55-grain .22-250 load. Always consult the manufacturer's provided ballistic data for your chosen ammunition.
Optimizing Your 22-250 Load for 55-Grain Bullets
While choosing a high-quality 55-grain bullet is important, optimizing your overall load contributes to better accuracy and performance:
-
Proper Barrel Break-in: A properly broken-in barrel ensures accuracy and consistency. Follow the manufacturer's instructions for breaking in your specific barrel.
-
Accurate Zeroing: Accurately zeroing your rifle at various distances is crucial for consistent shot placement. Utilize a quality boresight and target practice at different ranges.
-
Environmental Considerations: Altitude, temperature, and humidity can significantly impact ballistics. Adjust your aim accordingly.
-
Ammunition Selection: Select high-quality ammunition from a reputable manufacturer that consistently delivers accurate and reliable performance.
Conclusion
Understanding the ballistics of your .22-250 ammunition, specifically the 55-grain projectiles, is vital for achieving accurate and effective results. This information provides a starting point for understanding the factors that influence bullet performance and helps you optimize your load for optimal results. Remember always to prioritize safety and practice responsible firearm handling. Remember to always consult the ballistic data provided by the ammunition manufacturer for the most accurate information specific to your chosen load.
