[QUOTE="bigedp51, post: 1412933, member: 28965"] One of the biggest causes of neck runout is because the expander is locked down off center and pulls the case neck off center. Below is a Forster full length benchrest die with a high mounted floating expander. The expander enters the case neck while the neck of the case is held and centered in the die. Meaning this die can not pull the case neck off center, ensuring little to no neck runout. These Forster dies make the most concentric cases of any standard type full length die I have ever used.
