the chamber is the limiting factor to the brass... the elasticity of both the steels are within the limits of the chamber dimensions... I'm sure if you were trying to do a roll crimp, or super hot loads & your chambers were bigger than the brass ( out of tollorance ) you would have issues, but I expect my 250 or so cases to last me a life time, at my use...
BTW... it may take a bit more torque to resize if they are stretched much, but mine don't seem to stretch at all, with the pressures I'm running...
