This cartridge is designed for reliability and penetration in fight conditions. 5.56 ammunition usually employs heavier bullet weights and particular designs optimized for navy purposes.
This is the place the essential variations come into play:
One of the crucial important disparities lies within the stress scores. 5.56x45mm NATO cartridges are usually loaded to larger pressures than their .223 Remington counterparts. This elevated stress is an element that may affect chambering and barrel stress in sure firearms.
Key Variations
The opposite notable distinction resides within the chamber dimensions. Whereas the scale are shut, the chamber for a 5.56 barrel is barely bigger than the chamber particularly designed for .223 rounds. This distinction, notably within the throat space (the part of the chamber simply earlier than the rifling), impacts accuracy when firing .223 Remington in a 5.56 barrel.
Bullet weights and design additionally current variations. Whereas each cartridges can make the most of a wide range of bullet weights, 5.56 rounds could usually function heavier bullets and particular designs, reflecting their navy origin and designed objective.

One key distinction is the “throat” size. The throat is the part of the chamber simply earlier than the rifling. A 5.56 chamber often has an extended throat than a .223 chamber.
The Chamber
Subsequently, it’s important to grasp that utilizing .223 Remington cartridges in a 5.56 barrel could current sure efficiency features. In particular conditions, this might embrace lowered accuracy, notably at prolonged distances. It is a results of the bullet transitioning from the cartridge into the rifling. The longer throat could not permit the bullet to make the required contact with the rifling for the most effective outcomes.
The Threat of Utilizing .223 in a 5.56 Firearm
The stress variations, an element inherent between these two cartridge varieties, warrants cautious consideration. 5.56 ammunition is created to work with larger pressures in comparison with .223 Remington. Whereas capturing the latter in a 5.56 barrel is mostly protected, it is important to remember that the decrease stress related to the .223 cartridge could end in variations in bullet velocity and trajectory. This might probably change your level of influence.
Security Concerns
