I have two RCBS 5-0-5 scales, a Dillon's 'Eliminator' Scale, and a big Ohaus 3100. They all read within ~~ 0.1 gr the same.

In the 80s I figured out why some capacitors exploded on F16s. The caps I tested with ripple current and heat, I gave to a chemist to weigh weight change from Hydrogen outgassing. He handled the caps with tweezers, so he would not be weighing his finger prints. Reloading does not require that much accuracy nor precision.
