The Lyman 7810222 Multi-Caliber Outside Chamfer Tool handles a critical step in precision reloading: prepping the case mouth after trimming. If you're building accurate ammunition across multiple calibers, you know that a clean, properly chamfered case mouth improves bullet seating consistency and overall cartridge quality. This single tool works from .17 caliber up through .45 caliber, eliminating the need to buy separate chamfering tools for each caliber in your loading bench.
Chamfering the outside of the case mouth removes the sharp burrs left behind by trimming and creates a controlled beveled edge. That beveled edge helps the bullet seat smoothly and squarely, reducing runout and improving concentricity—factors that matter when you're chasing tight groups. Because you'll use this tool after every case trim, Lyman precision-machined and hardened it to withstand repeated use and maintain its cut geometry over time.
The tool's non-slip handle is designed for the repetitive work that reloading demands. Whether you're prepping brass for match-grade rifle loads, hunting ammunition, or anything in between, the outside chamfer is a step you can't skip if you want consistent results. At a practical level, having a multi-caliber chamfering solution means fewer tools cluttering your reloading press area and faster case prep when you're working with mixed brass or switching between calibers.
| Caliber Range | .17 through .45 |
| Function | Outside case mouth chamfering and burr removal |
| Handle Type | Non-slip |
| Model Number | 7810222 |
| Brand | Lyman |
The Lyman 7810222 is designed to chamfer cases from .17 caliber up to .45 caliber, making it suitable for most common rifle and handgun cartridges you'll reload.
Use the outside chamfer after you trim your cases to length. It removes the burrs created by trimming and bevels the outer edge of the case mouth, which improves bullet seating and helps reduce cartridge runout.
A properly chamfered case mouth ensures the bullet seats straight and consistently. This reduces runout and improves concentricity, both of which are important for accurate, reliable ammunition—whether you're hunting or shooting at the range.
No. The multi-caliber design means this single tool handles the full range from .17 to .45 caliber, so you don't need to buy multiple chamfering tools for different rounds.
