[QUOTE="AZShooter, post: 1389566, member: 5219"] IMO unless the brass is getting close to the end of the chamber I see no reason for any of it to be trimmed. My approach is to measure the end of the chamber and measure the brass after every sizing to see how the brass compares to that value. If it gets close I trim. Some chambers are so long the brass will be worn out before it stretches enough to be trimmed. I have some very accurate rifles and don't trim them to match in length even after a dozen firings unless necessary. Sinclair has a chamber length gauge for measuring the end of the chamber: [URL]https://www.sinclairintl.com/reloading-equipment/measuring-tools/case-gauges-headspace-tools/sinclair-chamber-length-gage-prod32925.aspx[/URL] video: [MEDIA=youtube]JKnXJxaAw2U[/MEDIA] I doubt you will see any difference in downrange performance from a sporter rifle with slightly varying case lengths. You could do a control and shoot the pet load with the shortest and the longest brass and compare results. If you see a difference please post back here and share. [/QUOTE]
