[QUOTE="woods, post: 382615, member: 6042"] Better. If you are running a .306" or so expander ball into the neck of a fire formed 7mm which should be ~.288", then the difference is .018" or so. That would mean your case neck is now much larger than the chamber neck and wouldn't fit. So then you size the neck down with your 7mm die but only to a point where you get the crush fit. Then you lock your die in and resize the rest. It would seem that the die setting would not leave much of the neck unsized (donut) and if it is adjusted too far down then you will start to size the case body. Sizing the case body would squeeze the case like a baloon and push the shoulder forward thus creating a crush fit. Are you sure you are not creating the crush fit by starting to size the case body and pushing the shoulder forward rather than bumping against the unsized portion of the neck? Lots of dynamics here [/QUOTE]
