I am a scale technician by trade, I calibrate and repair all makes and models, from small scientific, analytical balances (100g x .0001g) up to rail scales (400,000lbs x 50lbs). I owned a Denver Instruments DI-100 that measured out to .001 gns and used it for reloading. It did not same me any time, but it was precise!. I used to use a knife and split granules in half to get the reading as close to the desired weight as possible. Ever try that? That my friends is "splitting" hairs
I've used balance beams and don't care for them. I have the ChargeMaster and like it tremendously. I don't have to set it at eye level to make sure two lines line up each time. Give me a break, this is the 21st century. Embrace technology and move on.
My reloads are just as accurate now using the CM reading at .1gn as they were when I used the DI-100 reading at .001gn. Most people and their rifles can not shoot the difference! JohnnyK.
