Product Summary
The K&M PowerStroke V2 Expand Mandrel 6.5mm is an essential tool for precision reloaders who need to size their brass properly before neck turning. Because commercial dies lack standardized expander buttons, this mandrel ensures a consistent inside diameter by ironing out and slightly expanding the case neck. It is designed to work in tandem with the PowerStroke V2 Press Adapter and the K&M Microadjustable Neck Turner. This setup is ideal for preparing virgin or competition brass, preventing the brass from springing back too tightly during the turning process.
