RE: How many have check wieght?
I never bought a set of gen-u-ine weights...
I just weighed some bullets large and small...and then labeled the packages they are in. If you feel your scale has been damaged, just weight them again and compare the new weights to the weights you've already recorded on the packages... Really all your needing is to see if the scale has changed accuracy...
I've always had more than one scale around, but if you have a buddy that reloads, you can weigh your bullets on his scale too, and then compare thereadingsto yours...
