Ok, first, our cat knocked my RCBS 10-10 scale down from its shelf to the next shelf, about 18 inches. Now I find that I am having a hard time getting it to zero out. I run out of adjustment on the zero screw before it is zeroed. Is it possible to somehow knock it out of zero and secondly, it that a problem that can be recalibrated?

Second part of the question is this: If the current scale is messed up, what are the experiences out there with either a digital scale or with the scale/powder dispenser combos?
