That's a really interesting question. I thought I was the only "lucky" person.

I have an RCBS 5-0-5 I bought back in the 1980s which has developed some consistency issues. I can zero the scale, then tap the pan to start it swinging and it'll come back to .2 to .3 grains (guestimate) off zero. It didn't used to do that, it used to be absolutely reliable and predictable. For a long time, if it'd start acting "wonky" I would clean the blade and notch which totally fixed the problem. Now that isn't enough. I'm thinking about replacing it.
