Conclusion

The 300 blackout cartridge was designed to be used in a pistol-length barrel, and it performs best in that configuration. A shorter barrel will decrease the velocity of the bullet, and a longer barrel will not increase the velocity enough to make up for the increased bullet drop.

The ideal barrel length for the 300 blackout is between 4 and 6 inches.
