Perhaps Lee has solved those issues; I had those measures nearly 15-years ago before I bought my Redding measure.
Also, powder weights can vary with your technique on the powder handle; how long you take to dispense a charge, and how much powder is in the reservoir. I've found it helpful to develop a cadence for throwing charges, and I tend to keep my powder reservoir about 2/3 filled, re-filling after each block of 50 charged cases. That also has the effect of imposing a break in the action and reminding me to shine a flashlight into the filled cases in the loading block to ensure that each case received powder and to check for double charges.
You might also test to see whether a +/- .2gr variation has any effect on velocity with your loads and, if so, whether that effect is enough to warrant investing equipment and time eliminating the variation.
