I could see it changing as the scale warms....parts expand but I haven't seen it personally. I use a frankford arsenal I found somewhere on sale. I know they're cheap but everytime I've checked it against my beam scale it's been dead on.
It makes weighing the charges for my magnums a heck of a lot faster.
If the pain is lacking so is the discipline...
