Don't know if it is only terminology or not, but I NEVER try to WEIGH anything on a beam scale. After you zero it on a solid surface (not your loading bench, or it will move and lose zero everytime you run a round through your loader) you should set your target weight on the beam. When you dump your powder set it on the scale and it will be light, heavy, or, hopefully, right on zero. Keep adjusting your powder measure until you pretty much get zero everytime. When you develop confidence that the measure is throwing consistently, then weigh about every tenth round to see that nothing is changing. With a new scale or measure it may take quite a few rounds for me to develop confidence.
