A rifle barrel twenty-four inches long can increase bullet velocity by fifty percent
Science
Utilizing a twenty-four-inch rifle barrel can increase a bullet's muzzle velocity by fifty percent compared to shorter carbines, significantly extending the weapon's effective range and lethal energy.
A 24-inch rifle barrel allows for a more complete powder burn, accelerating projectiles to muzzle velocities of 900 meters per second. This increase is driven by the prolonged containment of expanding gases, which, according to Le Chatelier's principle, continues to push the bullet as long as it remains within the bore. In contrast, shorter carbines often exhaust unburnt powder into the air, sacrificing potential kinetic energy.
