Body Dies are designed to full length resize the case body and bump the shoulder position for proper chambering without disturbing the case neck. They are made without internal parts and intended for use only to resize cases, which have become increasingly difficult to chamber after repeated firing and neck sizing. Designed as a companion to the Bushing-style Neck Sizing Dies.
This body die permits precise shoulder bump (I use Redding Competition Shell Holders) along with Full Body Sizing when neck sizing only no longer permits chambering without excess force.
