    Hello Bersa brothers and sisters!

    I am just getting into reloading.
    The last few years I have been picking up the supplies.
    Most all I have is RCBS.
    Press is Rock Chucker Supreme.
    Just had my first lesson last night!
    The gentleman who taught me on his bench uses a powder measure and a mechanical scale.
    I do have the slide scale and a RCBS Rangemaster 1500.

    So I have two questions:

    1) What am I looking for in a good powder measure? Do you have any that you would recommend? I will be reloading both rifle and handgun with the bulk being handgun. And I like to go the next step up so I am not starting to get it down and realize the next step up would take care of a lot more.

    2) How accurate are the digital scales? Do you trust them? I realize my teacher was old school and he does not trust them. Yet my wife works at a chemical manufacturer and she talk to the plant employees and they felt digital scales were fine - you just made sure they were occasionally calibrated.

    At this point I do not feel the need of a progressive press since I will not reload to those types of capacities.
    It is mostly for plinking, target, home defense, and self defense.
    I do want to get the best accuracy as possible.
    Main calibers I will be reloading are .357 Mag, 38 Sp, 9MM, .44 Mag, .44 Sp, .223, 5.56MM, .22-250, and .243.

    Any advice in these areas is greatly appreciated.
    No matter how insignificant you feel it is, it may be significant to me!
    I have been perusing the reloading section of the forum reading about various components and tips.
    The thought of kidnapping Greg for a month did cross my mind!

    God bless!!

    Warning against what???

    While researching RCBS powder measures I see a warning at the bottom of the page for each one that states:

    WARNING: This product contains a chemical known to the State of California to cause cancer, birth defects, or other reproductive harm.

    http://www.rcbs.com/Products/Powder...s/Mechanical/Quick-Change-Powder-Measure.aspx

    Anybody know about this or what the chemical is?
    I tried researching on the internet but find nothing.
    Something in the plastic?
    Supposed to contain BPA?
    Could it be the anti gun crowd attempting to throw an invisible wrench into a machine they do not like?

    A quick check of Lee Powder Measures does not reveal a Cali Warning.

    I pretty much only use an electronic scale now. I have 2 PACT digital scales and they both are spot on with my Lyman M5 scale. I checked them against each other and they were pretty much spot on, too. I was looking at my records and came across these numbers. The first is comparing my first PACT scale with my Lyman M5 scale. I think I was weighing loaded .380 Auto rounds or maybe empty cases, I can't remember.
    1. PACT 144.4 gr.; M5 144.4 gr.
    2. PACT 143.7 gr.; M5 143.6 gr.
    3. PACT 143.6 gr.; M5 143.6 gr.
    4. PACT 144.1 gr.; M5 144.0 gr.
    5. PACT 142.9 gr.; M5 143.0 gr.
    6. PACT 143.8 gr.; M5 143.9 gr.
    7. PACT 144.6 gr.; M5 144.5 gr.
    8. PACT 143.1 gr.; M5 143.2 gr.
    After I got the second PACT scale I compared it with the first and got the following numbers:
    1. First PACT 308.5 gr.; Second PACT 308.6 gr. (second 20 gram check weight)
    2. First PACT 308.5 gr.; Second PACT 308.5 gr. (first 20 gram check weight)
    3. First PACT 161.7 gr.; Second PACT 161.7 gr. (chrome powder pan)
    4. First PACT 126.4 gr.; Second PACT 126.4 gr. (brass tone powder pan)
    5. First PACT 124.2 gr.; Second PACT 124.2 gr. (red plastic powder pan)
    I know this isn't a large volume of data, but with what measuring I did the PACT scales were within +/- 0.1 grain of the M5 scale and each other. That is the tolerance that PACT states for the scale and about what you will get when using a quality powder measure. Of course, with a powder measure you have to worry about the weight thrown changing as the volume in the hopper decreases, though a baffle in the hopper usually mitigates this.

    I am satisfied with my PACT digital scales, but they are the only ones I have tried. I can't speak to the cheaper scales that are made in China (the PACT is made in the USA).

    If you set up your analog scale correctly it will be right on every time, the digital scales have a + or - tolerance factor.
