how accurate are electronic scales?

my rcbs 5-0-2 beam scale is screwed up i can zero the beam and then weight a 180 150 55 grain bullet and it shows all them .5-.6 grain less in weight i have an old scale that is very accurate but takes 5 min to balance one powder charge out.
thinking about getting an elctronic scale someday and wondering how good they are accuracy wise. for what they cost i would think they should be very accurate.

    I have an RCBS Powder Pro electronic scale that I have used for several years now. It is very accurate, and it comes with weights to calibrate it, if necessary. Frankly, I will not go back to the balance-beam type scales again. Just don't use it near air-conditioning vents or near a fan as this has a tendency to cause the scale to drift.

    Better to have and not need, than need and not have.

    Also, some bullets being off by a grain or two is common, unless you are weighing a premium bullet. I shoot Nosler Ballistic Tips in my .270 and have found that they are very consistent. I see what you are saying though with all of the bullets being off by the same amount. The Powder Pro scale was worth the money.

    I have a Pact BBK that has had thousands of charges, bullets and cases weighed on it; and it still functions perfectly.
    Problems with electronic scales are usually caused by improper placement of the "tare" tray, proximity to RFI (radio frequency interference) sources like hands-free phones, scanners, baby monitors, or radio equipment, or certain envoronmental causes, like static electricity build-up, or a very slight breeze being present while calibrating the scale initially.
    Your beam scale may have accumulated dust on the beam, or on the poise (the agate "knife" that the beam rides on at the fulcrum).

    If you know it all; you must have been listening.WEAR EAR PROTECTION!

    I don't know about yours but both of my balance beam scales have a small place to put oil and a vane that goes into it. This makes it stop oscillating very quickly.

    I also use the RCBS electronic scale. I calibrate it EVERY time I turn it on,..this ensures consistency from loading to loading. It weighs great charges which are consistently sub .25moa in multiple rifles. Powder charge varainces are more forgiving than neck tension or seating depth variances. Buy a good digital scale,...they are faster to work with.


    why chase the game when the bullet can get em from here?....

    Very accurate.
    Diamond scales measure down to 1/100th of a carat.
    5 carats = 1 gram = 1 CC of water @ 20 degrees C
