Speed is not something near the top of the list.
I have a vintage beam scale that I use. It never needs batteries, it is very accurate (verified with weights) and I use the time that the scale is moving to sit and just look over what I am doing.
I want accuracy and good reloading.
In my advancing years, I need to be very careful not to rush thru my reloading.
AND dont mix grams up with grains.
be safe
