Lyman Brass Smith Bushing for Case Trim Xpress #17 .416 Rem Mag 8mm Rem Magag

The Lyman Brass Smith Bushing for Case Trim Xpress #17 .416 Rem Mag and 8mm Rem Mag is a precision accessory engineered for reloaders who demand consistent case trimming across magnum rifle cartridges. This spring-loaded bushing attaches to the Case Trim Xpress system and centers the case with the cutting tool, eliminating the need for separate pilots while delivering repeatable, square cuts on bottleneck magnum cases.

The #17 bushing specification is calibrated for .416 Remington Magnum and 8mm Remington Magnum cartridges—long-range hunting rounds that require tight case dimensioning for consistent chamber fit and optimal bullet seating. The spring-loaded design provides smooth cutting action without binding, allowing experienced reloaders to process approximately 15 cases per minute with minimal fatigue. This speed matters when working with premium magnum brass that represents significant material cost and requires meticulous attention to trim length specifications.

Long-range precision shooters and hunters working with magnum cartridges depend on case trim consistency to maintain chamber concentricity and bullet runout within acceptable tolerances. The Lyman bushing integrates seamlessly with the Case Trim Xpress platform, which is recognized in the reloading community for its efficiency in processing rifle brass. This bushing is a replacement part for users expanding their Case Trim Xpress system to additional caliber families or maintaining a dedicated setup for magnum ammunition production. Lyman's modular bushing system means you can quickly switch between caliber groups without replacing the entire trimming fixture.
