[QUOTE="dok7mm, post: 1418701, member: 90080"] The first thing I would have done is to have measured the overall length of the chamber. Brownell/Sinclair has the gauge to do it. Just a pin you slide in a shortened case neck. Will work with factory SAAMI chambers. Once this is found, set your trim .010" short of max length. Plus, I would have fired the new brass in your chamber before trimming. It often takes two firings to fully form to your chamber. Then, your base to datum length would have been practically identical. That's when I set up to trim, because SAAMI chamber neck lengths are notorious for being long. [/QUOTE]
