Concerning the other situation, the scenario adjustments considerably. Taking pictures 5.56 NATO ammunition in a .223 chambered barrel is usually not advisable. The tighter chamber of a .223 barrel will not be designed to deal with the upper pressures of 5.56 NATO ammunition. This could result in quite a few potential points.
The chance of elevated stress is a significant concern. The .223 chamber may limit the growth of the 5.56 spherical, resulting in elevated chamber stress. This could, in flip, result in numerous issues, from untimely put on and tear on the firearm to catastrophic failure.
One other hazard is the danger of case rupture. If the stress is just 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 usually safely shoot .223 in a 5.56 barrel, you typically ought to by no means hearth 5.56 in a .223 barrel.
Accuracy and Efficiency Implications
The first concern is security, however concerns concerning accuracy and efficiency additionally warrant examination. Even when protected, utilizing .223 Remington in a 5.56 barrel can generally 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 generally 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 dimension.
Nonetheless, accuracy might be affected by many components. The standard of the ammunition, the kind of rifling, the optics, the shooter’s expertise, and the climate are all issues that will affect accuracy. Particular person outcomes will at all times fluctuate relying on the precise barrel and the ammunition getting used. Some barrels may present little to no distinction in accuracy. Others may need a discernible distinction.
It is price mentioning that you simply may 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 often small, it may influence the bullet’s trajectory over longer distances.
