[QUOTE="Hugnot, post: 2914570, member: 115658"] My astute analysis of this ongoing situation is: Squashed brass! The brass needs to be trimmed. The brass might be within specs for trim length, but the chamber might be too short. The neck looks plastered with crud like powder & primer residue. This is the result of jamming excessive length brass into a short chamber. Upon firing the brass neck is prevented from expanding because it is jammed into the chamber neck/leade. A flared neck end is evident with a thin shiny area indicating contact. Powder gasses including primer residue & residue & other gush back along case body to bolt face resulting in messy firing(s). Additional doings that would support the excessive length idea are powder smudged brass sides & powder residue on bolt face. I respectfully submit that your brass needs to be trimmed shorter and after firing the brass necks should be nice, clean & shiny. [/QUOTE]
