The threaded shell holder locks the case down in the gauge so the cutter rides square against the case mouth, producing clean, repeatable trims time after time. The gauge is engineered to trim to the standard \u003cstrong\u003e2.600 to 2.620 inch\u003c\/strong\u003e case length for the cartridge, keeping fired brass within SAAMI spec and ready for resizing and reloading.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eManufactured from \u003cstrong\u003ehardened steel\u003c\/strong\u003e with a \u003cstrong\u003esilver finish\u003c\/strong\u003e, the gauge is built to last a lifetime of reloading use.
