Hornady 050140 Cam-Lock Multi-Caliber Case Trimmer

The Hornady Cam-Lock Multi-Caliber Case Trimmer is a centerpiece reloading tool for shooters who process brass across multiple calibers. Whether you're trimming .22 centerfire up through .50 BMG, this trimmer handles the job with precision and speed. The cam-lock mechanism secures cases firmly against the large cutter head while keeping them square—critical for consistent trim lengths that feed reliably and perform safely.

What sets this trimmer apart is the combination of thoughtful design and practical versatility. The frame is taller than earlier Hornady models, and the ergonomic handle makes long trimming sessions less fatiguing. Trim length adjustment is micro-precise via the fine-adjust knob on the cutter shaft, so you can dial in exactly the length your reloading manual calls for. The included pilot set covers seven popular calibers (.22, 6mm, .270, 7mm, .30, .38, .45), and optional pilots extend compatibility across the full spectrum from .17 to .50 caliber.

This is a manual, bench-mounted trimmer—you control the pace and pressure, which many reloaders prefer for the feedback and control it provides. Optional accessories like chamfering and deburring tools thread on in place of the cutter, letting you add those finishing steps without swapping equipment. A power adapter is also available if you want to motorize the trimmer later. Note that shellholders and pilots must be purchased separately and must be genuine Hornady items to ensure fit and safety.
