The Essential Drawback: Why They Merely Do not Combine
The reality stays: you can’t safely chamber or fireplace a 5.56 NATO spherical from a .300 Blackout rifle, or vice-versa. The results of trying to take action will be dire. The first purpose for this incompatibility lies within the dimensional variations between the 2 rounds, notably the case size.
Think about attempting to pressure an extended cartridge right into a chamber designed for a shorter one. The 5.56 case is considerably longer than the .300 BLK case. That is like attempting to suit a bigger puzzle piece right into a smaller area; one thing has to provide.
Here is a breakdown of the hazards:
- Chambering Points: The 5.56 cartridge will doubtless not totally seat throughout the .300 Blackout chamber. The bullet will doubtless be jammed into the rifling, stopping the bolt from utterly closing.
- Potential for Misfire or Chamber Obstruction: Even when the bolt does handle to shut, the 5.56 bullet could not correctly have interaction the rifling, resulting in a harmful scenario. The spherical could misfire, or the bullet could change into caught within the barrel.
- Catastrophic Failure: If a 5.56 spherical is one way or the other fired in a .300 Blackout chamber, the end result will be disastrous. The upper strain generated by the 5.56 spherical, when mixed with the restricted area, can simply result in a case rupture. This rupture can launch high-pressure gasoline and fragments of steel, doubtlessly inflicting extreme injury to the firearm and severe harm to the shooter. The barrel might burst. The receiver might fail. The shooter might be wounded or worse.
The variations in case size and bullet diameter imply that the 2 rounds are merely not interchangeable. The .300 Blackout is designed to make use of a .30 caliber bullet in a shorter case, whereas the 5.56 NATO is designed to make use of a .223 caliber bullet in an extended case. Forcing these two collectively is a recipe for catastrophe.
