I just ran my first 20 once fired .280AI cases through a properly set up full length resizing die (per manufacturer's instructions). The brass measured 2.131" before it was shot with a tame starting load to break in the barrel. The brass went into the resizing die at the same length of 2.131" and came out at 2.126". Being that the brass didn't stretch to chamber length on one light load, I did not expect to see the shoulder pushed back that far. Should I now anticipate a problem on the next loading with this brass because of the head clearance?
