This kit features the same components as the 50th Anniversary Kit, but we have replaced the Safety Prime with the Auto-Prime XR and a set of Auto-Prime Shell Holders. This kit is for those who prefer to prime off the press. Includes the new Breech Lock Challenger Press and one Breech Lock quick-change bushing. You get a complete powder handling system, with the most convenient and repeatable Perfect Powder Measure. Plus the Lee Safety Scale, the most sensitive and safest of all powder scales and fill your case with the included Powder Funnel.
