Hand Held Priming Tool Description The perfect companion to any single stage press-our handheld priming tool features a one-piece primer tray with an improved retaining system for the lid. It also sports integral molded bushings for ultra reliable function. The primer tray also eliminates the need for separate primer bushings. The system comes with an additional tray designed for use with RCBS shell holders. The body has been modified for easier change-over. The seater punch and spring are captured inside the priming tool; allowing shell holders and primer trays to be changed without removing spring and punch.
