Molybdenum Disulfide (MoS₂) Powder and Bullet Coating

Molybdenum disulfide (MoS₂) is a solid lubricant with exceptional properties that make it highly effective for coating bullets. It has been used by manufacturers like Norma and competitive shooters for years to improve bullet performance.

Properties of MoS₂

  1. Low Coefficient of Friction – MoS₂ significantly reduces friction between the bullet and the barrel, leading to less wear and lower heat buildup.
  2. High Load-Carrying Capacity – It can withstand extreme pressures, making it suitable for high-velocity rifle rounds.
  3. Thermal Stability – MoS₂ remains effective at high temperatures, preventing bullet deformation or excessive barrel fouling.
  4. Corrosion Resistance – It provides a protective layer that reduces oxidation and extends the life of both bullets and barrels.
  5. Bonding Ability – MoS₂ adheres well to metallic surfaces, ensuring a consistent lubricating layer without flaking or coming off easily.

Why Coat Bullets with MoS₂?

  1. Reduced Barrel Wear – The lower friction means less metal-on-metal contact, preserving the rifling for a longer barrel life.
  2. Increased Velocity Consistency – With smoother travel through the bore, bullets achieve more uniform velocities, improving accuracy.
  3. Lower Fouling – It prevents excessive copper or lead buildup in the barrel, reducing the need for frequent cleaning.
  4. More Consistent Ballistics – The reduction in friction and fouling helps ensure predictable performance, particularly in precision shooting.
  5. Reduced Heat Generation – Less heat means less thermal expansion of the barrel, contributing to consistent accuracy over longer shooting sessions.

How is MoS₂ Applied to Bullets?

The application process typically involves:

  • Tumbling bullets in a container with MoS₂ powder and Distilled water to ensure an even coating. Tumble time depends on tumbler and MoS₂ levels. Check every hour until an even coat is achieved and no copper jacket is left visible. Dry and polish off excess powder and water on a rag.
