RCBS 90377 Dry Case Neck Lube - Reloading Lubricant Kit

The RCBS 90377 Dry Case Neck Lube eliminates the sticky mess and inconsistent application issues that plague traditional wet case lubes during brass preparation. This precision-engineered dry lubricant system ensures smooth case neck expansion while maintaining consistent bullet seating pressure across your entire reloading batch.

What Makes This Different

Unlike liquid case lubes that can migrate into powder charges or create uneven coating thickness, this dry formulation provides controlled lubrication exactly where needed. The specialized compound reduces case neck tension by up to 40% compared to unlubricated brass while preventing the over-lubrication problems that cause hydraulic denting in bottleneck cases. Clean application means no residue cleanup between reloading sessions.

Key Features

• Dry powder formula eliminates liquid lube contamination risks
• Reduces case neck tension for consistent bullet seating pressure
• Compatible with all brass calibers from .17 to .50 BMG
• No cleanup required - leaves cases ready for immediate loading
• Temperature stable from -20°F to 150°F storage conditions
• Single application lubricates up to 500 case necks
• RCBS precision-tested formula prevents case mouth splitting

Bench rest competitors rely on this dry lube system to maintain shot-to-shot consistency in match ammunition. The controlled lubrication prevents the bullet seating force variations that can affect powder compression and overall cartridge length uniformity. High-volume reloaders appreciate the time savings from eliminating lube removal steps, while precision shooters value the consistent neck tension that contributes to single-digit extreme spread velocities.
