LEE Collet Die / Single Case Neck Sizing Die .30-06

LEE Collet Die / Neck Sizing Die .30-06

The LEE Collet Die set consists of a standard seating die and a neck sizing die; both die bodies are made of hardened steel, and each Collet Die set also includes a shell holder and a powder measure. The special feature of the Collet Die set is the adjustable neck sizing die; it only sizes the neck of the case via a collet. When raising the case into the die, the shell holder also pushes the collet upwards, which then compresses the neck of the case. Depending on how far you push the case into the sizing die, the case will be sized more or less. Lubricating the case is no longer necessary. The case is only deformed as much as required for seating the bullet. The more you size the neck of the case, the greater the extraction resistance of the bullet, and the tighter the bullet sits. The LEE Collet Die set is only suitable for new cases or those that have always been fired from the same firearm, as the body of the case is not sized. These die sets are not suitable for cartridges that are to be fired from semi-automatics or lever-action rifles.
