[QUOTE="Murtfree, post: 2396524, member: 111090"] I think what you are experiencing is completely normal and is just basic brass flow. Now that the case has been fired and stretched to fit your chamber and you force it back to specs, the ”extra size/stretch” has to go some where and it usually shows up as brass flow into the neck because it is the only place it can go. I find my cases do this fairly often especially when you are dealing with the first or second firing; I always anneal and trim after the first two firings. After that any excess brass relative to your chamber is mostly gone and the stretch is usually negligible. Cases with sharper shoulder angle like the Ackley’s tend to show less brass flow [/QUOTE]
