[QUOTE="kai, post: 1638260, member: 98994"] I bought several Sinclair Chamber Length Gauges to measure my various rifle chambers. [URL]https://www.brownells.com/reloading/measuring-tools/case-gauges-headspace-tools/sinclair-chamber-length-gage-prod32925.aspx[/URL] The Brownells website says:[I] "The differences between published trim lengths and the actual length of your chamber can be quite significant. You could be over trimming your cases by .030 inch or more. [/I] I discovered that my rifle's chambers are roughly .030" to .040" longer than the SAMMI (trim to) length." What is the ideal trimmed length of the case relative to the actual chamber length? [/QUOTE]
