Special 21st Century expander die bodies with window viewer.
The set up of an expander die has not been easier! The viewing window of this version of the die body allows the user to set the die for optimal mandrel use without “bottoming out”. You can see what is going on.
These two different size die bodies are machined out of 7075 Aluminum and then hard coated for durability.
Die body is machined internally to accept 3/8″ dia. shank expanders and is the standard 7/8″ x 14 tpi thread to use in reloading presses. Including Forster Co-ax
The STD (Standard) size body is ideal for most cartridges up to say a 30-06 case size. This unit has a black top cap.
The Long body for longer cartridge cases and magnum length stuff like a 338 Lapua. This version has a silver top cap.
This tool helps to keep your cases concentric during the expanding operation because the mandrel is allowed to free float inside the body to compensate for press ram and shell holder misalignment.
Aluminum Die Locking Ring has a nylon ball and set screw to hold in place which only takes a pinch with an Allen Wrench to secure. Locking rings works in Forster Co-Ax also.
