Concerning the other state of affairs, the state of affairs modifications considerably. Capturing 5.56 NATO ammunition in a .223 chambered barrel is usually not really helpful. The tighter chamber of a .223 barrel will not be designed to deal with the upper pressures of 5.56 NATO ammunition. This may result in quite a few potential points.
The danger of elevated stress is a serious concern. The .223 chamber would possibly limit the growth of the 5.56 spherical, resulting in elevated chamber stress. This may, in flip, result in varied issues, from untimely put on and tear on the firearm to catastrophic failure.
One other hazard is the chance of case rupture. If the stress is simply too excessive, the cartridge case can fail, releasing scorching fuel and particles. This may be extraordinarily harmful, probably inflicting damage to the shooter or others close by. Extraction issues, the place the spent cartridge case will get caught within the chamber, are one other potential results of overloading the barrel. These points could cause a delay within the firing cycle and probably require instruments to clear the malfunction.
The underside line is: whilst you can typically safely shoot .223 in a 5.56 barrel, you usually ought to by no means fireplace 5.56 in a .223 barrel.
Accuracy and Efficiency Implications
The first concern is security, however issues relating to accuracy and efficiency additionally warrant examination. Even when secure, utilizing .223 Remington in a 5.56 barrel can typically have an effect on accuracy.
The marginally longer leade in a 5.56 chamber, whereas designed to accommodate the upper pressures of the NATO spherical, can typically imply {that a} .223 bullet has to journey a brief distance earlier than participating the rifling. This hole can probably have an effect on the bullet’s trajectory and group measurement.
Nevertheless, accuracy will be affected by many elements. The standard of the ammunition, the kind of rifling, the optics, the shooter’s abilities, and the climate are all issues that will affect accuracy. Particular person outcomes will all the time differ relying on the precise barrel and the ammunition getting used. Some barrels would possibly present little to no distinction in accuracy. Others might need a discernible distinction.
It is price mentioning that you just would possibly expertise barely decrease velocities when utilizing .223 in a 5.56 barrel. That is primarily because of the decrease stress of the .223 Remington spherical. Whereas the distinction is usually small, it might influence the bullet’s trajectory over longer distances.
