I have a 5-10 RCBS beam scale and I am wondering if the magnetic Dampening Magnets can go bad after years of use because it is a Magnetic dampening scale. I have cleaned them with alcohol and I have leveled the unit and set it at zero, but when I bump the end of the needle arm is doesn't always go back to zero, sometime it sticks maybe one or two marks either above or below zero. Then if I bump the needle arm it again it will return to zero most of the time. That is why I am wondering if the magnets can weaken over time? Guess I should be asking RCBS Customer Service at this point, what do you think?
