The Redding CARBIDE 3-DIE SET for 40 S&W features Titanium carbide, which has the highest hardness of any readily available carbide, ideal for resizing cartridge cases.
Titanium carbide's microstructure is smooth and rounded, providing a non-galling surface that allows for lubeless resizing of cartridges.
The set includes a Titanium Carbide sizing die, an expander die, and a bullet seating die with a built-in crimp.
