300 RUM Ballistics Table: A Comprehensive Guide to Long-Range Performance
The .300 Remington Ultra Magnum (RUM) is a powerful cartridge renowned for its exceptional long-range capabilities. Understanding its ballistics is crucial for precision shooting and hunting at extended distances. This comprehensive guide provides a detailed ballistics table and explores the factors influencing its performance. Note that the data presented below is a generalization and can vary depending on several factors including: bullet weight, bullet design (BC), barrel length, twist rate, powder charge, altitude, and atmospheric conditions (temperature, humidity, barometric pressure). Always consult your specific load data from reputable sources before firing any ammunition.
Understanding Ballistic Coefficients (BC)
Before diving into the table, it's important to understand the concept of ballistic coefficient (BC). BC is a measure of a bullet's ability to overcome air resistance. Higher BC values indicate less air resistance and therefore, flatter trajectories and longer effective ranges.
Factors Affecting Ballistics
Several factors influence the actual ballistic performance of the .300 RUM. These include:
- Bullet Weight: Heavier bullets generally have higher BCs and retain more energy at longer ranges. However, they may have lower velocities.
- Bullet Design: The shape and construction of the bullet significantly impacts its BC and overall performance.
- Barrel Length: Longer barrels generally yield higher velocities.
- Powder Charge: The amount of powder used influences muzzle velocity. Incorrect powder charges can be dangerous. Always follow manufacturer recommendations.
- Environmental Conditions: Temperature, humidity, and air pressure all impact bullet trajectory.
Sample 300 RUM Ballistics Table (Approximate Data)
This table presents approximate data for a 180-grain bullet with a BC of 0.600 fired from a 26-inch barrel. These values should be considered estimates, and actual performance will vary.
| Distance (yards) | Velocity (fps) | Energy (ft-lbs) | Drop (inches) | Wind Drift (10 mph, right wind) (inches) |
|---|---|---|---|---|
| 100 | 3000 | 3600 | -1 | -2 |
| 200 | 2750 | 2900 | -5 | -7 |
| 300 | 2500 | 2300 | -12 | -15 |
| 400 | 2250 | 1800 | -23 | -26 |
| 500 | 2000 | 1400 | -38 | -40 |
| 600 | 1750 | 1050 | -57 | -57 |
| 700 | 1500 | 750 | -80 | -75 |
| 800 | 1250 | 500 | -107 | -95 |
| 900 | 1000 | 300 | -138 | -118 |
| 1000 | 750 | 150 | -173 | -142 |
