How many of you use a calibration weight on your beam scales? Also what weights are you using? I need some calibration weights just not sure where to get some that are marked in grains.

Thanks
 
I use the weight from my digital scale but one can get some here..

all I can seem to find is check weights in grams but cant find any in grains. Do you all just use the 10gram weight which is 154.32 grains and set the scale at 154.3?

Any suggestions?
 
Beam scales are calibrated in the drawing room, as the scale is designed, then built.
If the scale is set level, is undamaged and clean, just zero the setting, if need be, by the means designed for that scale and the scale will be accurate at all ranges.
I have many times weighed bullets, little bullets and big bullets, not to test the scale, but to test how accurate the bullets were made. Weigh a box of fifty and there will be some bullets over the specified weight and some under, but at the end, the average will be what it says on the box. Anything over ten bullets will get an extremely close average.
I have never had my old, Lyman beam scale, read anything except exactly what it was supposed to read.

That is akin to telling a machinist to use his ruler to calibrate a micrometer. Use the right tools for the job to get the best result.

You don't calibrate a micrometer, either. This was done when they were built. Any adjustment is to set them at zero, when they are closed.
