Purchased a box of 500 pieces of X-Treme 55gn FMJ .223 bullets. Just pulled a sample out to see how close they are in dimension. See attachment. Measured with my Mitutoyo 500-321 calipers. They readout in .0005 so that is what i recorded, trying to use same pressure while measuring them to get as good as they will measure. My scale reads out to the 0.02 grain so that is what i measured as well. (checked it with the 10 Gram calibration weight at start and finish, within 0.04 grain both times)
