I just had something happen that is completely puzzling. My OHAUS 1010 powder scale (a single beam balance scale) just quit working. Our neighbor's son came over to load some 223's for his up coming Javelina hunt and my powder scale just quit working. Right now there is a 50 some gr. lead bullet sitting in the pan, and the scale is set to zero grains, but the pan stays up, and the pointer stays down. It is like I have the scale set to weigh 100 gr. charges instead of zero and the pan does not move without my pushing it down. If anybody has experienced something like this and has an answer as to why or not please let me know. This is a balance beam scale not electric.
