Hornady Neck Turn Tool Mandrel 17 Cal Stainless Steel

The Hornady Neck Turn Tool Mandrel in 17 Cal is a precision stainless steel replacement mandrel designed for use with the Hornady Neck Turn Tool. This caliber-specific mandrel slips into the neck of a sized case to provide internal support while the outside of the neck is trimmed to a uniform wall thickness - a key step in precision case preparation that promotes concentric necks, consistent bullet seating, and improved accuracy downrange.

The base Hornady Neck Turn Tool ships with mandrels for the four most popular bottleneck calibers. 17 caliber is sold separately as a dedicated replacement mandrel sized at 0.172 inch in diameter, giving handloaders who work with .17 caliber bottleneck brass a properly piloted pilot for clean, repeatable neck turning.

The stainless steel construction provides a durable, wear-resistant working surface, and the polished silver finish lets the mandrel slide cleanly in and out of cases without marring the neck interior. This Mandrel is intended for handloaders who already own the main Hornady Neck Turn Tool body and need the 17 Cal mandrel for their bottleneck cases.
