[QUOTE="Bart B, post: 723515, member: 5302"] I don't think there's any difference in how much a case expands to the chamber dimensions between a new case, neck only sized fired one or a full length sized one. Even with a 5K CUP/PSI difference in peak pressure in the 50K to 60K CUP/PSI range that some claim will be the difference between these case types, the chamber is the same size and the case is pressed hard against its surfaces at peak pressure. They're all a crush fit in the chamber. It's been my experience that unless the powder charge is at least 10% below max, there's no evidence (primer sticking out past the case head) that the case doesn't expand to the chamber dimensions [/QUOTE]
