You are mistaken because you are using a junk scale.
I inherited 2 Lee balance beam scales and they both had poor dampening characteristics because Lee used cheap weak magnets.
If you buy the equivalent junky electronic scale you will be even worse off. For the most part a used RCBS 502, 505, 5-10 and 10-10 scales are all much better than the Lee and are more reliable than any digital scale under $500. Many long range accuracy shooters use digital scales but they run in the range of $800 to $1000.
You are right the Lee scale is not so hot but cheap digitals can be worse.
BTW I was given a new Dillon Dterminator digital scale about 15 years ago and it was worthless. After 8 years passed it was still new sitting in my closet. Dillion brought out a next generation scale and I sent mine back. The replacement works fine but I had to wait 8 years for the state of the art to be useful.
I also have the RCBS 750 made by Pact. It works ok but I do not trust either for one pass weighing. You need to pick up and reweigh many times to verify the scale did not stick. So my digitals are confined to weighing brass and bullets. Powder is weighed with 6 or 7 scales that I have that were made by Ohaus for Lyman and RCBS. I broke one Lee scale experimenting on it. The other is stored because it is not worth the postage to give it away.
