Thread: Projectile vs barrel length

No, what has a calculation is twist rate for projectile weight. Even shooting a heavy projectile with the right twist rate the barrel length will only determinate how fast you will need to "push the projectile" to achieve the velocity that will keep your projectile efficient out to long or extreme ranges.
Apparently, depending on how far you need to shoot the faster projectiles will go they will be supersonic for longer and efficient to the desired distance, cutting or having a short barrel length will only say you will need a "hotter" load to make your rig efficient.
