1.5 - 2.5 miles
A 6.5 Creedmoor bullet can travel between 1.5 and 2.5 miles (2,400 - 4,000 meters) depending on factors like muzzle velocity, angle of fire, and wind. It maintains supersonic speed - crucial for accuracy - to around 1,200 meters, after which it becomes transonic and then subsonic.
Factors Affecting Distance
- Muzzle Velocity: Higher velocity extends range.
- Angle of Fire: Optimal angles maximize distance.
- Wind: Significant wind drift impacts accuracy at long range.
- Bullet Weight & Shape: Heavier, streamlined bullets travel further.
- Air Density: Altitude and temperature affect air resistance.
Supersonic vs. Subsonic Travel
A 6.5 Creedmoor bullet's performance changes as it slows.
- Supersonic: Travels faster than the speed of sound (Mach 1). Stable and accurate.
- Transonic: Around the speed of sound. Less predictable.
- Subsonic: Slower than the speed of sound. Affected by wind and gravity; reduced accuracy.
Maximum Range Comparison
| Method | Approximate Maximum Range (meters) | Accuracy |
|---|---|---|
| Flat, unobstructed terrain, 30° angle | 3,800 | Moderate |
| Elevated position, 10° angle | 4,000+ | High (with precise calculations) |
| Level ground, optimal conditions | 2,400 | High |
Ballistic Coefficient
The ballistic coefficient (BC) measures a bullet's ability to overcome air resistance. A higher BC indicates better long-range performance. 6.5 Creedmoor bullets generally have a high BC, contributing to their extended effective range.
