Corbin Mfg. .230 cal Rebated boattail die set
Bullet swaging dies for forming rebated boattail bases. This one is .230 cal. Also included is a .30 cal to .230 cal jacket reducing die. This would cost you over $500 plus wait time from Corbin Mfg. The jacket reducing die is missing the punch, can be easily replaced from Corbin Mfg. or from a competent machinists.
