The Lyman 7821704 Case Trim Xpress Bushing #4 delivers consistent case trimming for precision handloaders who demand accurate cartridge dimensions. This replacement bushing maintains tight tolerances essential for uniform case preparation across multiple reloading sessions.
What Makes This Different
Unlike generic trimming components, this precision-machined bushing features hardened steel construction with exact dimensional specifications for the Case Trim Xpress system. The #4 size designation corresponds to specific cartridge families, ensuring proper case mouth engagement and consistent trim length. Standard trimming methods often produce variations of 0.005" or more, while this bushing maintains tolerances within 0.002" for professional-grade results.
Key Features
- Hardened steel construction resists wear after thousands of trimming operations
- Precision-machined internal dimensions for exact case mouth fit
- Compatible with Lyman Case Trim Xpress trimming systems
- #4 size specification for designated cartridge calibers
- Drop-in replacement design requires no modifications or adjustments
- Maintains consistent trim length within 0.002" tolerance
- Heat-treated surface prevents dimensional changes over time
Competitive shooters and precision handloaders rely on this bushing for match-grade ammunition preparation. The consistent case length achieved translates directly to improved accuracy and reliable chambering across bolt-action rifles and semi-automatic platforms. Weather conditions and temperature variations do not affect the bushing's dimensional stability, making it suitable for year-round reloading operations.
