my RCBS digital scale is fairly old.. maybe pushing a decade... may be time to see what is out there for new stuff with better electronics...

funny.. bout the power... yes you can get "dirty" electricity... all that means is that you have a lot of noise in the sinusoidal wave or the frequency is not a constant 60 Hz. you may be able to get a filter to plug into the wall and then plug the scale into the filter... surprised because most scales and such should have a filter built into them.

whenever my cell phone rings my scale goes nuts... freaked me out the first time it happened... had never done it before but i got a new phone a few months back and now it does... weird...

and yes the ATF has rules on how much gunpowder a person can have at one time...
