Botnia MoS2 50g

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.
