Lyman Brass Smith Bushing for Case Trim Xpress #7 .303 British 7.62 x 39 30-40 Krag 6.5 Grendel

The Lyman Brass Smith Bushing for Case Trim Xpress #7 is a precision reloading accessory engineered to process .303 British, 7.62 x 39, 30-40 Krag, and 6.5 Grendel bottleneck cases. This spring-loaded bushing works in conjunction with the Case Trim Xpress system to center and support cases during trimming operations without requiring external pilots, delivering consistent case length across large batches while maintaining production speed.

The bushing design enables a smooth, effortless cutting stroke—a critical factor for reloaders processing multiple caliber families in succession. The spring-loaded mechanism absorbs inconsistencies in case handling and reduces operator fatigue during high-volume trimming sessions. Users can expect to trim approximately 15 cases per minute with this bushing, making it suitable for both dedicated reloading benches and mobile ammunition manufacturing operations. The compact profile (1.6 x 0.8 x 3.4 inches) minimizes storage footprint while maintaining rigidity during the trim cycle.

This bushing is essential for reloaders working with less common rifle calibers—particularly those in the 7.62 x 39 and 6.5 Grendel categories, which demand precise case preparation before loading. Law enforcement ammunition technicians and precision rifle competitors rely on Lyman bushings to ensure dimensional consistency across case lots, directly impacting chamber fit and velocity uniformity. The #7 designation indicates compatibility with the Case Trim Xpress platform, so verification of your equipment model before ordering is recommended.
