[QUOTE="bigedp51, post: 1296904, member: 28965"] I have seven different type and make .223 dies, and my Forster bushing bump die produces the most neck runout. And my Forster full length bench rest die produces the least neck runout, along with my RCBS dies equipped with the Forster expander and spindle assembly. Neck sizing dies do not fully support the case body like a full length die does. Also when you reduce the neck diameter .004 or more with a bushing die it can induce neck runout. Meaning bushing dies work best with custom tight neck chambers with neck turned brass. At the Whidden custom die website they tell you that non-bushing full length dies produce the most concentric ammunition. [IMG]http://i.imgur.com/Y3IiYL5.jpg[/IMG] [/QUOTE]
