K&M PowerStroke V2 Expand Mandrel 20 Caliber

Size your case properly with the K&M PowerStroke V2 Expand Mandrel, Mandrel Holder and PowerStroke V2 Press Adapter before neck turning. Virgin/competition Brass isn't quite ready to Neck Turn when you buy it. And the commercial die manufacturers have no set standards for the Expander button in their dies. Large variations from manufacturing to manufacturing and even within a given manufacturing makes it necessary to properly size the inside diameter before turning. Don't be fooled by slick talk
