[QUOTE="boomtube, post: 563410, member: 9215"] All reloading beam scales are very fine instruments; very sensitive and accurate. Without a clue as to how much 'error' you may be seeing or what scale you're using we really don't have a lot to go on to make a serious suggestion. Thing is, beam scales just don't change all by themselves, that's their strong point, but they do get dirty and damaged and misadjusted. Do this: Gently clean the beam and its notches, the pan, pan hanger, bearings and pivot knives with a tooth brush and something like Windex. Use a magnifying glass to look at the pivot knives. You don't want to see burrs or nicks on the sharp edges. If you do see burrs they will have to be ground away. The pivot bar should be unbent - perfectly straight across and at 90 degrees to all sides of the beam. Place the empty pan on the hanger and adjust the left side screw foot so it's perfectly zeroed to the beam pointer. Lightly touch the pan and see if it returns to zero; repeat that several times to insure it doesnt stop on one side or the other of zero. If it does, you have damaged the pivot or bearings OR you don't have the beam properly centered between the bearings so end friction is making the beam bind. [/QUOTE]
