The only way to improve on the design and technology of the X-Bullet was to add something to it. The new XLC™ Coated Bullets have been coated with the Barnes high-tech, solid dry film lubricated coating. This coating reduces friction in the bore, reduces fouling for high velocity shooting, reduces heat build-up and improves accuracy. XLC™ Coated Bullets provide all the benefits of the X-Bullet and more. 50 per box This is a Bullet or Projectile only, NOT loaded ammunition.
