Description
21st Century Expander Die Body
For those seeking the next level in accuracy, expanding case necks using precision mandrels has become the norm, the result is improved neck tension consistency and concentricity. The practice of using a mandrel, rather than an expander ball that is pulled up through the neck also eliminates the stretching that this process can induce.
The 21st Century Expander Die Body will fit multiple cases, the standard size fits cases up to 30-06 in length whist large works for 30-06 and above in length.
The die also helps to keep your cases concentric during the expanding operation, the mandrel is allowed to free float inside the die body to compensate for press ram and shell holder misalignment, the aluminum cap retains expanding mandrel and allows the floating function
21st Century Dies will accept both 21st Century and Cortina Precision mandrels.
- Choose either of the two lengths available of these bodies. Longer cartridges (like a 7mm Rem Mag for example) would work better in the longer body.
- Die body is machined internally to accept 3/8″ dia. shank expanders.
- 7/8×14 thread to suit standard reloading press.
- Stainless Steel
- Mandrels Sold Separately
