Lee Precision Micrometer Full Length Die Set Features The Lee Micrometer Full Length Die Set for 7mm Backcountry centers on a Full Length Sizing Die paired with a Micrometer Bullet Seating Die letting handloaders dial in seating depth with repeatable precision rather than guessing at adjustments between loading sessions. The Universal Flaring Die preps case mouths for smooth bullet seating without deforming brass which matters most when working with mixed range brass of varying wall thickness. Lee notes that steel cases require substantial effort to full length resize so ample high performance case lubricant is essential to avoid galling or stuck cases. The included load data and instructions give new and experienced reloaders a reliable starting point for safe consistent loads. Rounding out the set are a Universal Shell Holder and a Powder Dipper both practical additions that reduce the need for separate purchases when setting up a reloading bench for this cartridge. The shell holder is sized to work with the included dies for a smooth repeatable workflow from sizing through seating. For hunters whose magazine length limits overall cartridge length and prevents the bullet from touching the rifling Lee recommends adding their Factory Crimp Die to help restore accuracy. This set gives reloaders a complete well-rounded starting point for working up 7mm Backcountry ammunition at home.
