How Fast is a.308 Bullet?
The.308 Winchester cartridge is a popular choice among hunters and shooters, known for its versatility and accuracy. But one question that often comes up is: how fast is a.308 bullet?
The Speed of a.308 Bullet
The speed of a.308 bullet depends on several factors, including the type of ammunition, the rifle’s barrel length, and the atmospheric conditions. However, in general, a.308 bullet can travel at a speed of around 2,600-3,000 feet per second (fps).
Ammunition Type
The type of ammunition used can significantly affect the speed of a.308 bullet. Here are some common types of.308 ammunition and their corresponding velocities:
- Full Metal Jacket (FMJ) ammo: 2,500-2,800 fps
- Soft Point (SP) ammo: 2,600-3,000 fps
- Hollow Point (HP) ammo: 2,800-3,200 fps
- Match ammo: 2,900-3,200 fps
Rifle Barrel Length
The length of the rifle’s barrel can also impact the speed of the bullet. A longer barrel can generate more muzzle energy and increase the bullet’s velocity. Here are some approximate velocities for a.308 rifle with different barrel lengths:
- 16-inch barrel: 2,400-2,600 fps
- 20-inch barrel: 2,600-2,900 fps
- 24-inch barrel: 2,900-3,200 fps
Atmospheric Conditions
Atmospheric conditions, such as temperature, humidity, and air pressure, can also affect the speed of a.308 bullet. For example, a bullet fired on a hot day may travel faster than one fired on a cold day. Here are some approximate velocities for a.308 bullet fired at different temperatures:
- 80°F (27°C): 2,700-3,000 fps
- 60°F (16°C): 2,600-2,900 fps
- 40°F (4°C): 2,500-2,800 fps
Bullet Weight
The weight of the bullet can also impact its speed. Heavier bullets tend to travel slower than lighter bullets. Here are some approximate velocities for.308 bullets of different weights:
- 150-grain bullet: 2,600-2,900 fps
- 168-grain bullet: 2,500-2,800 fps
- 175-grain bullet: 2,400-2,700 fps
Table:.308 Bullet Velocities
Here is a table summarizing the approximate velocities for a.308 bullet:
| Ammunition Type | Velocity (fps) |
|---|---|
| FMJ | 2,500-2,800 |
| SP | 2,600-3,000 |
| HP | 2,800-3,200 |
| Match | 2,900-3,200 |
| 16-inch barrel | 2,400-2,600 |
| 20-inch barrel | 2,600-2,900 |
| 24-inch barrel | 2,900-3,200 |
| 80°F (27°C) | 2,700-3,000 |
| 60°F (16°C) | 2,600-2,900 |
| 40°F (4°C) | 2,500-2,800 |
| 150-grain bullet | 2,600-2,900 |
| 168-grain bullet | 2,500-2,800 |
| 175-grain bullet | 2,400-2,700 |
Conclusion
In conclusion, the speed of a.308 bullet can vary depending on several factors, including the type of ammunition, rifle barrel length, atmospheric conditions, and bullet weight. By understanding these factors, shooters can optimize their rifle’s performance and achieve better accuracy and range. Whether you’re a hunter or a target shooter, knowing the speed of your.308 bullet can make a big difference in your shooting experience.
