Hornady Trimmer Pilot #50 .500

• Caliber-specific pilot fit: The #50 pilot is sized for .500 / 12.70 mm bullet diameter, helping keep the case mouth centered during trimming for straighter, more consistent results.
• Cam Lock Trimmer compatibility: This pilot is made for the Hornady Cam Lock Trimmer, giving reloaders a direct-fit accessory for caliber changes without modifying the trimmer setup.
• Steel construction: The steel body stands up to repeated contact with brass during case preparation, supporting dependable alignment over long loading sessions.
• Supports uniform case preparation: By guiding the case mouth on the cutter, the pilot helps produce more even trim lengths, which matters for consistent crimp, neck tension, and overall ammunition uniformity.
• Compact single-purpose accessory: As a dedicated case preparation component, it is easy to keep with caliber-specific tooling and swap in when moving between different cartridge families.

About the Cam Lock Trimmer & Pilots Series

The Hornady Cam Lock Trimmer & Pilots series is built around a simple idea: make case trimming more repeatable while keeping caliber changes straightforward. Within Hornady’s reloading lineup, this family sits in the brand’s case-care and case-preparation range, alongside the tools reloaders use to trim, chamfer, deburr, and maintain brass for repeated loading cycles. The system is intended for handloaders who want a practical bench setup for routine brass maintenance rather than a one-caliber-only tool.

The series centers on the Cam Lock Trimmer, which uses standard Hornady shell holders and interchangeable pilots so the same trimmer can be adapted to many cartridge sizes. That modular approach is the main advantage of the platform: the trimmer provides the cutting function, while each pilot supports proper case-mouth guidance for the caliber in use. In practice, that helps the cutter track more consistently and reduces the chance of uneven trimming. For reloaders working across several chamberings, the Cam Lock Trimmer & Pilots series offers a durable, bench-friendly system focused on repeatable case length control and easy caliber-specific setup.

About the Hornady Trimmer Pilot #50 .500

The Hornady Trimmer Pilot #50 .500 is a caliber-specific accessory for reloaders preparing brass with the Hornady Cam Lock Trimmer. Sized for .500 inch / 12.70 mm bullet diameter, it supports the case mouth during trimming so the cutter stays better aligned as material is removed. That guidance is a small part, but it has an important job: it helps produce cleaner, more uniform case mouths and more consistent trim length from case to case.

For large-caliber reloading, consistency in case preparation matters because trim length affects later steps such as chamfering, deburring, neck tension, and crimp uniformity. A properly matched pilot helps keep the trimming operation controlled instead of allowing the case mouth to wander on the cutter. In practical terms, that means less variation introduced at the brass-prep stage and a smoother workflow when processing batches of cases.

The pilot is made from steel, which suits a part that sees repeated insertion into case mouths during normal bench use. Its dedicated design also makes caliber changes simple: when moving to a different cartridge family, the reloader swaps to the corresponding pilot rather than changing the trimming system itself. For anyone loading .500-caliber cartridges on Hornady’s Cam Lock platform, the #50 pilot is the correct accessory for keeping case trimming properly centered and repeatable.

About Hornady

Hornady Manufacturing was founded by Joyce Hornady in 1949 in Grand Island, Nebraska, where the company is still headquartered today. It remains a family-owned American manufacturer focused on bullets, ammunition, reloading tools, and related accessories. That broad product range is important in the reloading category because Hornady develops not only projectiles and loaded ammunition, but also the presses, dies, measuring tools, and case-preparation equipment used to build consistent handloads.

Within reloading equipment, Hornady is especially well known for practical bench systems such as the Lock-N-Load bushing design, which speeds die changes, and for a long-running catalog of tools covering case prep and cartridge assembly. The company expanded its reloading-tool presence further after acquiring Pacific Tool Company in 1971. That background helps explain why accessories such as trimmer pilots are treated as part of a complete reloading system rather than as isolated parts.
