Caveats to the Basic Rule: It is important to grasp why it is not a easy “sure.” A number of elements want consideration:
Stress Issues: Whereas the 5.56 chamber can sometimes deal with .223 ammunition, the decrease stress of the .223 spherical is probably not optimized within the chamber. The chamber could not get the total energy and velocity.
Accuracy and Efficiency: You would possibly discover a slight lower in accuracy or efficiency. The longer leade within the 5.56 chamber, whereas helpful for five.56 rounds, can typically affect the accuracy of the .223 spherical as a result of the bullet has to journey additional earlier than participating with the rifling.
Barrel Put on: Whereas not a serious concern normally, there *might* be elevated barrel put on, significantly if utilizing .223 ammunition solely in a 5.56 chamber.
Efficiency Variations: The bullet might need a barely decrease velocity than standard.
Taking pictures 5.56 in a .223 Chamber: A Harmful Proposition
Conversely, making an attempt to shoot 5.56x45mm NATO ammunition in a rifle chambered for .223 Remington is a essentially harmful apply. This isn’t advisable.
The Core Hazard: The .223 Remington chamber is designed to accommodate the stress specs of .223 ammunition. Taking pictures 5.56 ammunition in such a chamber can expose the firearm to dangerously excessive pressures.
Potential Unfavorable Outcomes: The implications of exceeding stress limits are extreme.
Overpressure Occasions: The potential for exceeding the design stress limits of the firearm is important.
Firearm Catastrophes: Excessive pressures may cause catastrophic failures, probably resulting in:
Burst Barrels: The barrel might burst or rupture.
Chamber Rupture: The chamber itself might explode.
