Expand Iron Complete for .50 caliber

Includes press adapter and .50 caliber expand mandrel. Size your brass as you normally would do for reloading and then drive the expand mandrel through the case neck to size it properly to fit on the neck turner pilot. You may find it necessary to remove the expander ball from your sizing die. The 7/8-14 threaded adapter fits your normal reloading press but requires the 1 1/2 to 7/8 thread adapter for the typical larger press. The expand mandrel will iron out and slightly expand the case neck so the brass will spring back to the correct size needed to neck Turn your brass.
