What Ammo Does an AR-10 Shoot?
When it comes to the AR-10, one of the most popular and versatile rifles in the world, understanding the ammunition it shoots is crucial. Whether you’re a seasoned shooter or just starting out, knowing the different types of ammunition that an AR-10 can handle can greatly enhance your experience. In this article, we’ll delve into the various calibers and types of ammunition that the AR-10 is designed to fire, providing you with a comprehensive guide to what this rifle can do.
Caliber Options
The AR-10 is available in a variety of calibers, each offering different performance characteristics. The most common calibers include:
| Caliber | Origin | Typical Bullet Weight | Typical Bullet Velocity |
|---|---|---|---|
| 7.62x51mm NATO | NATO | 150-175 grains | 2,800-3,000 fps |
| 6.5mm Creedmoor | Custom | 140-160 grains | 2,800-3,100 fps |
| 6.8 SPC | Custom | 115-125 grains | 2,800-3,200 fps |
| .308 Winchester | Custom | 150-175 grains | 2,500-2,800 fps |
Each of these calibers has its own strengths and weaknesses, and the choice of caliber often depends on the intended use of the rifle. For example, the 7.62x51mm NATO is a powerful and versatile round that excels at long-range engagements, while the 6.5mm Creedmoor is known for its exceptional accuracy and flat trajectory.
Types of Ammunition
Once you’ve decided on the caliber, it’s important to understand the different types of ammunition available for your AR-10. Here are some of the most common types:
- Full Metal Jacket (FMJ): This is the most common type of ammunition and is designed for target shooting and training. FMJ bullets have a solid copper jacket and a lead core, which makes them ideal for practice sessions.
- Full Metal Jacket, Pointed (FMJ-P): Similar to FMJ, but with a pointed nose, FMJ-P bullets are designed to expand on impact, making them suitable for hunting and self-defense.
- Soft Point (SP): SP bullets have a soft nose that expands on impact, increasing their effectiveness at longer distances. They are often used for hunting and self-defense.
- Hollow Point (HP): HP bullets have a hollow nose that expands on impact, creating a larger wound channel. They are highly effective for hunting and self-defense, but can be more expensive than other types of ammunition.
- Armor-Piercing (AP): AP bullets are designed to penetrate armor and are used primarily for military and law enforcement applications.
When choosing ammunition for your AR-10, it’s important to consider the intended use of the rifle and the specific requirements of your shooting environment. For example, if you’re planning to use your rifle for hunting, you’ll likely want to choose a bullet with good expansion characteristics, such as a SP or HP. If you’re using your rifle for self-defense, an AP bullet may be a better choice.
Loadings and Cartridges
In addition to the type of bullet, the loading and cartridge also play a significant role in the performance of your AR-10. Here are some key factors to consider:
- Cartridge Case: The cartridge case is the container that holds the propellant and bullet. Common cases include the 7.62x51mm NATO, 6.5mm Creedmoor, and .308 Winchester.
- Propellant:
