[QUOTE="mrultramag, post: 853146, member: 4467"] And my guess as to how dented cases happen in the 7 rum; a mild load that does not develop pressure fast enough to seal the neck to the chamber but does develop enough to seal the case body to the chamber. The gas that has sneaked back past the neck collapses the shoulder of the case. and as you have stated there are many contributing variables such as brass hardness, etc that can help contribute to this happening. When the conditions are right-it happens. JMHO but its just a wild assed guess mostly. [/QUOTE]
