Boat Tail

Posted in: Shooters Glossary

A bullet with a boat tail (or boattail, boat-tail) has a tapered feature on the back, allowing it to flow more efficiently through the air. Projectiles that taper down in the back move faster for longer, as they allow the displaced air that is moving around the projectile to reset closer to where it was before the bullet pushed it aside. Similar to how a wing comes to a pointed edge on its backside, allowing air to fully come back to its original position, a boat tail projectile attempts to allow air to move back to where it was.
