Adaptor assembly for converting a case sizing die assembly to a bullet seating die assembly

摘要

Various commercially available ammunition case sizing die assemblies consist of a die base and a subassembly which is threadedly installed in the die base. The subject adaptor assembly is configured to be installed in the sizing die assembly die base. As a result, a case sizing die assembly can be converted to a bullet seating die assembly by removing the subassembly of the case sizing die assembly and installing the subject adaptor assembly in its place. The subject adaptor assembly is made up of a rod and a lock ring. The rod has a knurled knob at one end, a cylindrical portion at the other and a threaded portion between. The lock ring threads onto the threaded portion and has a set screw in it to lock the lock ring in desired positions. The cylindrical end has a cavity in it in which the bullet is held during seating of the bullet.
