While there are a number of manufacturers that produce bushing dies the one that most Kiwis know are the Redding Type S bushing dies which are available in either neck or FL size versions, the FL bushing die is the most widely used. These take standard Wilson bushings or the Redding ones, steel or TiN coated, carbide bushings are also available but only in 6mm and in a very narrow range of sizes.
