The tighter dimensions of the .223 chamber, coupled with the upper pressures generated by .556 NATO ammunition, can create a harmful state of affairs. That is the place the true hazard emerges.
The potential dangers of utilizing .556 NATO in a .223 Remington barrel embody:
- Extreme Strain: This will trigger the brass casing to rupture, resulting in a doubtlessly catastrophic failure of the firearm.
- Bulging of the Chamber: The chamber partitions could increase past their design limits.
- Injury to the Barrel: The barrel can bulge, crack, or burst.
- Threat of Damage: The shooter and anybody close by are at a excessive danger of damage from escaping fuel or particles.
