The longer throat in a 5.56 NATO chamber permits the bullet a slight quantity of “free journey” earlier than partaking the rifling.
One other main distinction lies within the working strain. 5.56 NATO ammunition is often loaded to greater pressures than .223 Remington ammunition. The upper strain is instantly linked to the will for elevated efficiency in navy situations. This distinction in strain can have vital implications when contemplating compatibility. For example, a .223 Remington cartridge, designed for a decrease strain restrict, would possibly expertise strain spikes and create points if fired in a chamber that’s particularly designed for the upper strain of a 5.56 NATO spherical. The upper strain is an element that should all the time be thought of to take care of the security of each the shooter and the firearm.
These dimensional and strain variations are designed to enhance one another, guaranteeing dependable and protected operation for each cartridges when used of their supposed platforms. Nevertheless, these traits additionally deliver up vital issues for taking pictures the 2 completely different sorts of ammunition.
Taking pictures the .223 in a 5.56 NATO Rifle: A Certified Sure
The central query of this text: are you able to safely and successfully fireplace .223 Remington ammunition in a rifle chambered for five.56 NATO? The quick reply is sure, with caveats.
Most often, .223 Remington ammunition will be safely fired in a 5.56 NATO chamber. The marginally bigger dimensions of the 5.56 NATO chamber typically accommodate the .223 Remington cartridge with out creating vital strain points. Nevertheless, that doesn’t imply that this apply is problem-free.
The first challenge is that it may well have an effect on accuracy. The longer “free journey” in a 5.56 NATO chamber, initially designed for the longer bullet utilized in navy rounds, can result in decreased accuracy when utilizing .223 Remington ammunition.

Whereas typically protected, it’s crucial to know that using .223 Remington in a 5.56 NATO chamber doesn’t all the time ship optimum efficiency. Shooters would possibly discover a slight distinction in accuracy and muzzle velocity.
The Reverse: A Agency No
The scenario is markedly completely different when contemplating the reverse state of affairs: firing 5.56 NATO ammunition in a rifle chambered for .223 Remington. The reply here’s a definitive “no.”
The first concern is security. The 5.56 NATO cartridge is designed to function at a considerably greater strain than the .223 Remington. When this higher-pressure ammunition is fired in a chamber designed for a decrease strain, it may well result in a harmful overpressure scenario. The rifle would possibly expertise a catastrophic failure, doubtlessly inflicting critical damage to the shooter and anybody close by.
