[QUOTE="redneckdan, post: 1874895, member: 8932"] I do something similar, for example forming 6 creed from 243 or 25-06 from 270. I trim a case 30 to 40 thou short and use it to find the exact headspace. Then I take an untrimmed case and bump it .010 shorter headspace and start trimming it .005 at a time, insert it in the chamber and GENTLY try to close the bolt. Once the bolt closes I use that number as the chamber max OAL. I trim .010 shorter than this number. For example my 25-06 closes on a case @ 2.515", I trim to 2.505". Common trim length is 2.484 or .031" shorter than my chamber. [/QUOTE]
