Each rounds are exceptionally fashionable, particularly within the realm of AR-15 model rifles. Their visible similarities typically result in a important query: are you able to swap them? This text is designed to offer you the entire understanding you want.
Understanding the Cartridges: 5.56x45mm NATO versus .223 Remington
Let’s begin by dissecting the gamers on this ammunition drama. These two rounds are very shut kin, and in some ways, they seem practically an identical at first look.
The .223 Remington cartridge, which dates again to the Nineteen Sixties, was developed as a varmint spherical, designed for prime velocity and flatter trajectories. The 5.56x45mm NATO spherical, then again, is a navy cartridge. Adopted as the usual ammunition for the NATO alliance, it was designed to satisfy particular navy necessities.
One of the crucial notable traits of those two is the bullet diameter. Each cartridges share the identical diameter. The bullet usually measures .224 inch throughout. This shared attribute can additional improve the confusion.

However whereas these two rounds might appear to be twins, the similarities masks some essential variations that may have real-world security implications on the subject of **are you able to shoot a 5.56 by way of a .223** rifle.
Key Variations: Stress and Chamber Dimensions
The first divergence between these two rounds lies within the stress at which they function and the particular dimensions of the rifle chambers designed to deal with them. These seemingly delicate variations have a major influence on efficiency and, most significantly, security.
The 5.56x45mm NATO spherical is designed to function at a better chamber stress than the .223 Remington. This implies the military-grade 5.56 spherical generates extra drive when ignited. Whereas exact stress figures can differ relying on the particular load, the distinction is important sufficient to warrant cautious consideration. Larger pressures translate into larger drive pushing the bullet down the barrel.
The chamber of a rifle is the part of the barrel the place the cartridge sits earlier than being fired. Each .223 and 5.56 barrels characteristic chambers designed to obtain their respective ammunition. Nonetheless, the chamber dimensions, particularly the leade (or throat) of the chamber, are totally different.
The leade is the part of the barrel simply in entrance of the chamber the place the rifling begins. The leade size in a 5.56 chamber is usually longer than that present in a .223 chamber. The leade offers the bullet a little bit of “working begin” earlier than it engages the rifling. In a .223 chamber, the leade is shorter. This shorter leade means the bullet engages the rifling sooner.
Here is why the leade issues. While you fireplace a spherical, the bullet should journey a tiny bit earlier than it hits the rifling. The longer the space to the rifling, the extra leeway there’s for the stress to construct and settle. When the bullet hits the rifling, it causes the bullet to cease shifting ahead within the barrel barely and start to spin within the barrel, inflicting the stress to spike even greater than regular. The longer leade within the 5.56 permits the stress to develop regularly. Nonetheless, the shorter leade in a .223 chamber may cause a sudden and important stress improve.
The upper stress of a 5.56 cartridge can create an issue when fired from a .223 chamber. The outcome can typically imply exceeding the protected stress restrict of the .223 rifle.
The longer leade in a 5.56 chamber permits for a bit extra “slop” with an extended bullet, whereas the .223 is a little bit tighter with a shorter bullet.
Compatibility: Can You Hearth 5.56 in a .223 Rifle?

When the 5.56 spherical is fired in a .223 chamber with its shorter leade, the bullet encounters the rifling extra shortly. This earlier engagement of the bullet with the rifling creates a bottleneck, inflicting stress to spike. This spike can exceed the protected working limits of the .223 rifle, doubtlessly inflicting injury.
This extreme stress can even scale back accuracy. The bullet’s trajectory might develop into much less constant because of the elevated stress, resulting in extra dispersed groupings.
Most severely, firing 5.56 ammo in a .223 rifle can doubtlessly injury the rifle. The elevated stress may cause a wide range of issues, together with:
- Bulging of the barrel: This deformation can occur because the chamber experiences excessive stress.
- Issue extracting spent casings: This could manifest as a caught case, indicating excessive stress is at play.
- Barrel cracking: Extended use of the fallacious ammunition can finally result in barrel failure.
- Full barrel rupture: Within the worst-case eventualities, a chamber overload may cause the barrel to blow up.
