Target, Recessed, 11 Degree, Concave or Recessed. Pistol Barrels can be crowned to many different degrees including a 90 step. Crowning can greatly improve accuracy by insuring that the muzzle is free from any imperfections and allowing exciting gas pressure to be delivered uniformly and evenly across the muzzle face.

Barrel Crowning might be one of the best things one can do to improve accuracy. A perfectly crowned rifle barrel diverts gases in an even manor and leaves a clean surface for the bullet to exit from. Typical target Crown at 11 Degree or Hunting at 45 Degree.
