Additionally the crown serves another important function. As the bullet exits the muzzle propellant gases escape. The crown serves as a guide for the gases to follow. Uneven pressure around the base of the bullet caused by a nick, flaw or irregularity in the crown can push the bullet base slightly off line as it exits the muzzle effecting accuracy. A clean and even crown is an important part of very accurate rifles regardless of caliber.
