Can You Shoot 223 out of a 5.56 Gun?
The debate about shooting 223 out of a 5.56 gun has been a topic of interest among firearms enthusiasts and owners for a long time. The answer to this question is not a simple "yes" or "no," as it depends on several factors. In this article, we will dive into the details and explore the possibilities.
What are 223 and 5.56?
Before we dive into the nitty-gritty, it’s essential to understand the difference between 223 Remington and 5.56x45mm. 223 Remington is a specific cartridge that is designed for civilian and sporting use, while 5.56x45mm is a military cartridge used in AR-15 rifles and other firearms.
What’s the difference between 223 and 5.56?
Here’s a breakdown of the key differences:
| 223 Remington | 5.56x45mm | |
|---|---|---|
| Case length | 1.76 in (44.7 mm) | 1.76 in (44.7 mm) |
| Case diameter | 0.375 in (9.53 mm) | 0.375 in (9.53 mm) |
| Rim diameter | 0.375 in (9.53 mm) | 0.375 in (9.53 mm) |
| Maximum pressure | 55,000 psi (379 bar) | 62,000 psi (427 bar) |
| Ballistics | Designed for smaller, lighter bullets (up to 55 gr) | Designed for heavier bullets (up to 70 gr) |
As you can see, both cartridges share similar dimensions, but the 5.56x45mm has higher maximum pressure and is designed for heavier bullets. The 223 Remington is designed for smaller, lighter bullets and has a slightly lower maximum pressure.
Can You Shoot 223 out of a 5.56 Gun?
Now that we’ve discussed the differences between the two cartridges, let’s address the question directly. In general, it’s not recommended to shoot 223 out of a 5.56 gun, especially if the rifle is designed for military use. Here’s why:
• Pressure issues: The 5.56 gun is designed to handle higher pressures than the 223 Remington. If you shoot 223 out of a 5.56 gun, you may not be able to handle the increased pressure, which could lead to premature wear or even catastrophic failure of the rifle.
• Compatibility issues: The 223 Remington is designed to fit a specific chamber dimension, while the 5.56x45mm is designed for a different chamber dimension. Shooting 223 out of a 5.56 gun could lead to issues with bolt lift, chambering, and extraction.
• Performance issues: The 223 Remington is designed for smaller, lighter bullets, while the 5.56x45mm is designed for heavier bullets. Shooting 223 out of a 5.56 gun could result in reduced accuracy and penetration due to the lighter bullet.
• Safety issues: Shooting 223 out of a 5.56 gun could also pose a safety risk, as the increased pressure and heat generated by the firing process could cause the rifle to malfunction or even lead to accidental discharges.
However, There are Some Exceptions
While it’s not recommended to shoot 223 out of a 5.56 gun, there are some exceptions:
• Some modern rifles: Some modern rifles, such as the AR-15, are designed to accommodate both 223 Remington and 5.56x45mm cartridges. These rifles are designed with a chamber that can accommodate both cartridges, and are often marked as "5.56x45mm/223 Remington."
• Specialized bolt carriers: Some specialized bolt carriers are designed to handle both 223 Remington and 5.56x45mm cartridges. These bolt carriers are typically designed for use in bolt-action rifles and are specifically marked as "223 Remington/5.56x45mm."
• Custom conversions: In some cases, a gunsmith may be able to convert a 5.56 gun to shoot 223 Remington by re-chambering the rifle and installing a new barrel. However, this process requires specialized knowledge and tools, and is not recommended for the average gun owner.
Conclusion
In conclusion, while it’s not recommended to shoot 223 out of a 5.56 gun, there are some exceptions for specific rifles and bolt carriers. It’s essential to understand the differences between 223 Remington and 5.56x45mm cartridges, as well as the limitations and risks associated with shooting 223 out of a 5.56 gun.
