The PUNCH-HX is a cruciform or x-shaped punch used either in a configuration for the core swage die, or the core seating die (or rebated boattail die) to make a cross-cut in the core. This helps the bullet expand on impact at lower velocity, with a more evenly distributed mushroom. When used in a core swage die, the space between the segments will of course be collapsed when the core is later swaged into a jacket. Lubricants or thin plastic or paper strips inserted into the slots prior to seating will prevent the segments from re-joining under pressure. When used in the core seating die or the BT-2 final rebated boattail forming die, the core is extruded forward, becoming longer. It is highly desirable to bond the core to the jacket with Corbin Core Bond so that the grip of the core on the eight sides of the four punch blades does not pull the core back out of the jacket on ejection. The core must be made of soft lead or other easily deformed material to avoid breaking the blades. Likewise, the end of the core must be preformed as a smooth, flat surface. If the core is cut and dropped into a jacket, or into a core swage die, and immediately compressed with the X-punch, the blades may be torqued to the side with enough force to snap them. When entering a smooth, flat soft lead core, the force is all in the downward direction, parallel to the punch axis, so there is little or no sideways torque on the thin blades. When the punch is used as intended, it is more than strong enough for a lifetime of bullet making. It is a key tool for making effective subsonic bullets used for hunting or defense.
