Lyman Case Trim Xpress Bushing #4 - 300 Blackout / 17 Rem Fireball

The Lyman Brass Smith Case Trim Xpress Bushing #4 is a replacement steel trim bushing for the Lyman Brass Smith Case Trim Xpress power case trimmer. Sized to bottleneck rifle case shoulders, Bushing #4 fits 300 Blackout (7.62x35mm) and 17 Remington Fireball cases.

The bushing is spring-loaded to ride against the case shoulder, supporting the case against the trimmer's ultra-sharp carbide cutter for a smooth, concentric cut. This pilotless design lets the Brass Smith Case Trim Xpress process roughly 15 cases per minute with its variable-speed motor, while the high-visibility orange finish makes the bushing easy to identify on a crowded reloading bench.

Bushing #4 is made in the USA and is intended as a dedicated replacement or additional bushing for the Brass Smith Case Trim Xpress system. The trimmer base unit is sold separately.
