There is accuracy, then there is consistency. My beam scales are WAY more consistent than my digital scales. But, they both have their uses; I mass load plinking ammo with the digital (Gempro) to get it done quicker, but always use my trusty beam scale for accuracy / hunting loads where I am close to max pressure and/or want to be extremely consistent.
Beam scales might not display "actual" weight with a high degree of accuracy, but are extremely repeatable with their values (given you use the same surface and level perfectly). Remember, for years people tried to copy Jack O'Connor's highly accurate loads and were getting extremely different numbers. It was found after Jack's death that his favorite scale was off by 2 grains.
So actual weights are not as important as consistent weights for a given scale. It was also brought up earlier in this thread that calibration weights are often not correct. Another one of the dozens of reasons why you should always work up your own loads rather than copy someone else's.
