I have a RCBS balance scale and I have always had a confidence problem with the 5 grain steps on the big weight. They are just TOO close together and 5 grains can put you WAY over the top. So, what I do is this: After I set up my powder measure, I throw 10 charges into the powder pan and then measure that. If I was off by 5 on the scale, I'll be off by 50 on this check. That, I have confidence in being able to see! It has not happened ... yet, but this technique also allows me to home in on the right charge anyway, so it is a permanent part of my routine.
Be Safe,
Saands
