I have been seeing these, but there are some models that advertise .10 grain accuracy. I see that they all have very high shipping costs, relative to bid price. I havent decided to try one because of the potential downside if it ever went bad and I did not know it.
I use a Lee scale that came with my kit, it does what they say it will do. It measures the same weight repeatedly. What more can I ask for. I read a lot of criticisms of the model, but never any concrete examples where it failed to do its job.
An electronic scale would be easier to weight loads, but I dont weigh loads, I balance loads, so the electronic scale isnt going to make the trickle process any faster.
