[QUOTE="woods, post: 592088, member: 6042"] What caliber and was the brass new brass, once fired or fired multiple times What signs, do you have pics and how did you determine the signs .010" is not un-normal for an unbelted case going from a new case to a fired case. My Steyr 30-06 is .011". When you say the "shoulders had been pushed back too far", what was the difference in the measurements between the cases with the shoulders pushed back too far and a new case? A little more info Normally it takes so little pressure to expand the brass case in comparison to the pressures inside the chamber that it has little to no effect on pressure and velocity. [/QUOTE]
