Sinclair International 6.5mm (0.263") Carbide Expander Mandrel

Introducing the Sinclair International 6.5mm (0.263") Carbide Expander Mandrel, a precision tool engineered to elevate your reloading consistency and efficiency.

Yields Closer Tolerances and More Lubricity:

These expander mandrels are meticulously ground from solid carbide stock, a choice that results in significantly closer tolerances and superior lubricity. Carbide's inherent properties also make it highly effective at resisting galling, which can otherwise leave behind unwanted material and scratch the inside of your case necks, compromising their integrity.

The precise shape, finish, and size of this mandrel are the culmination of years of practical use and extensive experimentation by experienced handloaders. Sinclair expander mandrels are designed to be exactly 0.001" smaller than the bullet diameter, ensuring optimal performance.

Versatile Applications for Precision Reloading:

• Prior to Neck Turning: Using this expander mandrel before neck turning perfectly sizes the case to fit your neck turning mandrels, ensuring uniform material removal.
• Prior to Bullet Seating: Employ it before bullet seating to achieve more concentric necks and attain perfect neck tension, both critical for accuracy.

All Sinclair Mandrels are specifically designed for seamless integration with the Sinclair Expander Die and all Sinclair Neck Turning Tools, forming a cohesive system for advanced reloading.
