Lyman 7862000 Universal Case Trimmer .17-.458 Caliber Precision Tool

The Lyman 7862000 Universal Case Trimmer delivers consistent case length preparation across calibers from .17 to .458. This bench-mounted trimmer ensures uniform case dimensions for improved accuracy and reliable chambering in both rifle and handgun cartridges.

What Makes This Different

Unlike basic case trimmers that require multiple pilots and shell holders, the Lyman Universal system accommodates the widest caliber range with fewer components. The precision-ground cutter head maintains sharp edges longer than standard carbon steel alternatives. Spring-loaded case holder automatically centers cases for consistent trimming length within 0.001 inch tolerance.

Key Features

• Universal caliber compatibility from .17 to .458 with minimal pilot changes
• Precision-ground cutter head with replaceable cutting edges
• Spring-loaded case holder ensures automatic centering
• Adjustable length stop for repeatable case trimming
• Heavy-duty cast iron base reduces vibration during operation
• Quick-change pilot system speeds caliber transitions
• Compatible with standard shell holders and collets

Reloaders processing high volumes benefit from the trimmer's consistent performance across extended sessions. The robust construction handles heavy-duty use while maintaining precision tolerances required for match-grade ammunition. Competition shooters rely on uniform case length for consistent powder charges and bullet seating depth. The trimmer's accuracy proves essential for long-range precision loads where case preparation directly impacts group size.
