Check out this weapons video to see how to prepare a .223 case with the RCBS Case Prep Center.
The RCBS Case Prep center can be fitted with a Lee Case Trimmer Cutter that has been slightly modified and a Lee Case Length Gage. This adds trimming to the list of case preparation functions and allows the RCBS Case Prep Center to do almost everything that needs to be done to a piece of brass.
Tumble clean the brass, process the brass through the multiple stages on the RCBS Case Prep Center and it's ready to be reloaded with a primer, powder and bullet. Approximately 150 brass cases can be processed in an hour, including trimming to length, chamfering inside and outside the case neck and preparing the primer pocket.
The Hornady Primer Pocket Reamer Cutter Head reams the primer pocket to the correct diameter, including the removal of any military primer pocket crimp, and chamfers the entrance to the primer pocket to facilitate the entry of the new primer into the primer pocket. Redding makes a very nice primer pocket uniformer that will ream the primer pocket to the proper diameter and also cut the primer pocket to the correct depth. The Redding Primer Pocket Uniformer is a bit pricey at $30, but carbide cutting tools are expensive. They also last a long time.
