Product Summary
The K&M PowerStroke V2 Expand Mandrel 8mm 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 the inside diameter is correctly sized to account for the elasticity of the brass. It works in tandem with the Mandrel Holder and PowerStroke V2 Press Adapter to iron out and slightly expand the case neck. This setup is specifically designed to be the perfect companion to the K&M MICROADJUSTABLE Neck Turner for achieving consistent, high-quality results.
