[QUOTE="Joe King, post: 678074, member: 47325"] A bushing neck dies allows you to size only the case neck to a specific dia, thus controlling both neck tension on the bullet and less working of the case neck and at the same time leaving the case a is (fire formed to your chamber). I full lenght die sizies the entire case, in doing so it sizes the neck down a greater amount than the neck die and then as you remove the case from the FL die it pulls the neck over an expander ball. This last step is where a FL die can contribute to bullet runout/ poor concentricity of the loaded round. There is one other die design out there that has a good following which is the Lee collet neck die. How it works is, as the case is forced into the die it pushes the collet up into a tapered bushing. The collet then squeezes the neck down onto a mandrel of a specific for cal size. It's actually a pretty clever design, just leaves some thing to be desired in regards to quality, but it works and works well by my personal experience. It cost about $21 through midway Vs. $ 68+ plus for the Redding or Forester bushing neck dies [/QUOTE]
