The Lyman Case Length/Headspace Gauge for 6.5×55 Swedish (Lyman part no. 7990339) gives handloaders a fast, repeatable way to check two of the most important dimensions in bottleneck rifle brass. Lyman recommends inspecting every resized case before it goes back into a loaded round, and this gauge is the simplest way to do it. Simply drop a case into the gauge to confirm it falls within the safe headspace window and hasn’t stretched past the maximum allowable case length. It’s a must-have companion tool for any 6.5×55 Swedish reloading bench, whether you’re prepping brass for a hunting rifle or a precision target gun.

Key Specifications

• Chambered specifically for the 6.5×55 Swedish cartridge, so it drops directly into your existing case-prep routine without extra fitting.
• Weighs about 0.12 lb, light enough to keep at the bench or in a range bag alongside your other case-prep tools.
• Checks both case length and headspace in a single gauge, replacing two separate go/no-go checks with one tool.

Frequently Asked Questions

What does this gauge actually measure? It checks that a resized 6.5×55 Swedish case falls within Lyman’s safe headspace range and has not exceeded the maximum allowable case length.

What should I do if a case fails the check? Lyman recommends destroying any case that shows excessive headspace rather than attempting to load or fire it.
