The RCBS Bench Mounted Primer Pocket Swager is a dedicated bench mounted tool that makes the removal of primer pocket crimps a simple task. This rugged tool requires 35 percent less force than other tools on the market to complete the same task. A hardened steel rod supports the case from the inside allowing the case to float for perfect alignment with the hardened steel swager head. All a reloader has to do is rotate the case down into position and with a pull and push of the handle, the job is done.
