Now the great break through, OIL-FREE SHOCK HAMMERS:
Weights measured with a brand new mechanical balance beam scale agreed well with the digital/electronic scale. For example, two bullets that weighed exactly 400.0 gr each on the electronic scale weighed 399.9 gr for one and 400.1 g for the other on the balance beam. Same two-bullet average for the two scales: 400 grains. Those were the lightest two of the "400-gr" Shock Hammers encountered in 50 bullets. Both came from the second 25-count box of bullets.
The balance beam is more laborious but the digital is close enough for sorting "light" bullets from "right" bullets, in a bi-modal distribution.
