Can You Shoot 223 in a 5.56 Gun?
When it comes to shooting rifles, there are a multitude of options available in the market. Two of the most popular calibers used in rifles are 223 Remington and 5.56x45mm NATO. While they are similar, they are not exactly the same, and it’s essential to understand the differences between them. In this article, we will explore whether it’s possible to shoot 223 in a 5.56 gun and what factors you should consider before doing so.
What’s the Difference Between 223 and 5.56?
Before we dive into whether you can shoot 223 in a 5.56 gun, let’s understand the differences between the two calibers.
| 223 Remington | 5.56x45mm NATO | |
|---|---|---|
| Cartridge length | 40.7mm | 43.9mm |
| Case capacity | 27.2 gr H2O | 30.3 gr H2O |
| Bullet diameter | .224 in (5.56 mm) | .224 in (5.56 mm) |
| Muzzle velocity | 2,970 ft/s (907 m/s) | 3,050 ft/s (930 m/s) |
| Muzzle energy | 1,300 ft-lbs (1,763 J) | 1,400 ft-lbs (1,897 J) |
As you can see, the main differences between the two calibers are the cartridge length and case capacity. The 5.56x45mm NATO has a longer cartridge length and a slightly larger case capacity, which allows it to generate slightly more muzzle energy and velocity.
Can You Shoot 223 in a 5.56 Gun?
Now that we understand the differences between the two calibers, can you shoot 223 in a 5.56 gun? The short answer is yes, but there are some caveats.
223 in a 5.56 Gun: What to Expect
If you decide to shoot 223 in a 5.56 gun, here are some things you can expect:
- Reduced accuracy: The 223 cartridge is designed for a specific rifle, and using it in a 5.56 gun may affect the accuracy of the rifle. The difference in cartridge length and case capacity can cause the bullet to not seat properly, leading to reduced accuracy.
- Increased pressure: The 5.56 gun is designed to handle the higher pressure of the 5.56 cartridge. Shooting 223 in a 5.56 gun can cause the pressure to build up, potentially leading to damage to the rifle or other components.
- Potential for increased noise: The 223 cartridge is designed to produce less noise than the 5.56 cartridge. Shooting 223 in a 5.56 gun can cause the noise level to increase, potentially disturbing others.
When to Shoot 223 in a 5.56 Gun
While it’s generally not recommended to shoot 223 in a 5.56 gun, there may be situations where it’s acceptable:
- Target shooting: If you’re shooting at paper targets at close range, the difference in accuracy may not be noticeable. In this case, shooting 223 in a 5.56 gun may be acceptable.
- Hunting: If you’re hunting small game, such as varmints or coyotes, the 223 cartridge may be sufficient. In this case, shooting 223 in a 5.56 gun may be acceptable.
- Convenience: If you have a 5.56 gun and a 223 cartridge, shooting 223 in the 5.56 gun may be convenient. However, this should be done with caution and at your own risk.
Conclusion
In conclusion, while it’s possible to shoot 223 in a 5.56 gun, it’s not recommended. The differences in cartridge length and case capacity can affect the accuracy and performance of the rifle. However, there may be situations where shooting 223 in a 5.56 gun is acceptable. It’s essential to consider the factors mentioned above and use caution when shooting 223 in a 5.56 gun.
Recommendations
Before shooting 223 in a 5.56 gun, make sure to:
- Check the manufacturer’s recommendations: Check the manufacturer’s recommendations for the specific rifle and cartridge. Some rifles may be designed specifically for 5.56 cartridges and may not be suitable for 223 cartridges.
