Can You Shoot 7.62x39mm Out of a .308 Winchester (7.62x51mm) Rifle? A Definitive No.
The short answer is a resounding no. Attempting to fire a 7.62x39mm round in a .308 Winchester (7.62x51mm) rifle is extremely dangerous and could result in serious injury or death. The cartridges are simply not compatible.
Let's break down why this is such a disastrous idea:
Key Differences Between 7.62x39mm and .308 Winchester
While both cartridges use a bullet of roughly the same diameter (.311 inches), the crucial differences lie in their case dimensions and overall length:
-
Case Length: The .308 Winchester cartridge is significantly longer than the 7.62x39mm cartridge. This is the most important factor. The .308 Winchester's longer case will not fit into a chamber designed for the shorter 7.62x39mm.
-
Case Diameter/Shoulder: The case shape and shoulder angle differ as well. Even if you could force the smaller 7.62x39mm cartridge into the .308 Winchester chamber (which you shouldn't even attempt), the case wouldn't properly align with the firing pin or chamber walls.
-
Pressure: .308 Winchester operates at significantly higher pressures than 7.62x39mm. A 7.62x39mm round fired in a .308 Winchester chamber is likely to cause catastrophic failure of the rifle, resulting in the rifle bursting apart.
Potential Consequences of Mismatched Ammunition
The dangers of attempting this are severe:
-
Chamber Rupture: The most likely outcome is the chamber of the rifle failing due to the excessive pressure from firing a round that doesn't fit properly. This can send pieces of the firearm flying, causing serious injury or death to the shooter and bystanders.
-
Bullet Obstruction: The bullet might not leave the barrel properly, causing the rifle to jam or explode.
-
Barrel Damage: Even if the round manages to fire, the improper chambering can damage the rifle's barrel, rendering it unusable.
-
Personal Injury: Shrapnel from a ruptured rifle, burns from escaping gases, and other injuries are all significant risks.
Identifying Your Cartridge
It is crucial to correctly identify your ammunition and firearm before attempting to fire them. Pay close attention to the markings on both the casing and the firearm itself. If you have any doubts, consult a firearms expert.
In conclusion: Never attempt to shoot 7.62x39mm ammunition from a .308 Winchester rifle. It is incredibly dangerous and could lead to severe consequences. Safety should always be your top priority when handling firearms.
