[QUOTE="bigedp51, post: 1525275, member: 28965"] One of the main reasons of neck runout happens when the expander is locked down off center. The high mounted floating Forster expander enters the case neck when the case neck is held and centered in the neck of the die. You can use any manufacture of resizing die and remove the dies expander and then use a separate expander die and reduce neck runout. Dies that lock and center the expander in a collet have far less neck runout than dies that do not self center. Below a cheaper Lee sizing die can produce less neck runout than a Redding or RCBS die.

And I can understand why many reloaders complain about expander drag when using Redding's longer expanders.
