I rely on a couple Belding&Mull's for the bulk of my loading. I find that one is a little better for measuring small pistol powder charges than the other one - sharper cutting surfaces, some small difference in the geometry, voodoo maybe? It's the one that I gravitate to. Small charges of flake powder are very uniform, but I'll admit to double checking with a scale if said charges are going into small case target loads (ie: .22WCF), otherwise it's uniformity is plenty sufficient for my handgun shooting.

My Harrell's Schuetzen is relegated to matches/experimentation at the shooting bench with "our" powders, and it's marvelous. I tried it with Unique for .45ACP loads and it was A-ok.

I made a measure out of brass and teak wood for measuring pistol powders, based loosely on the design of the old Pacific measure. I'll brag that it is very accurate/uniform. Downside is separate rotors must be made for each charge and so far I've only made three.

What is this “modern” of which you speak?  I think a B&M is the most modern measure I use.  My Little Dandy may be a little newer.
There are (or were) several rotor type powder measures designed for use with pistol loads. I like the old Lyman Accu-Measure as well as the older Pacific Pistol measure in addition to the newer Little Dandy.  When you decide on a charge that works, find (or modify) a rotor to throw that charge over and over and over with boring accuracy.

So, I'm setting up several powder measures on the bench.

I'm also setting up several powder scales.  Not concerned so much with "precise accuracy" but for "repeatability".

The test will be ONE flavor of powder, multiple repetitions, different times of day.

22Hornet, 22K-Hornet, 221 (rifle), .223 and .219 Zipper.  Powders to be determined by accuracy competition. 

Issues developed using flake powders (Unique et al.).  Going through the process of load development  by ensuring EACH stage of reloading is consistent.  I'm assuming that powder weight is right much critical.

Unless you want to make a small cavity measure like I did or drill the single cavity measures like are illustrated. I would get a Little Dandy with a 1,2,3 and 4 rotor (2.3 - 3.0 gr Unique). They are harden steel and won't wear.

The only other option is to use a pistol measure insert, like the Redding that I used before I made mine. They have a 5/16 cavity. The Ohaus Dou measure, also has a 5/16 cavity but, it's at a angle, with a larger shear area and no micrometer adjustment.

My Redding mic settings for Unique are .050 = 1.0 gr & .250 = 3.0. B'eye is almost identical. I used my Redding for a few years, untill I built the small cavity one. It worked well enough to get 1" groups, at 100, with 4.5 gr of Unique, in a 25/20R single shot.

So I've dug out several scales.  One electronic one varied +0.1 to -0.1 gr weighing a 53 grain bullet some 25+ times.

So that identifies (for that scale) a +/- 0.10 variability that will occur. 

Yes, the scale read-out went to 0.01 increments.

That's variability.  Accuracy?  I'll dig out some CALIBRATED weights and adjust as needed.

I find precise measures to be better than accurate measures.  What is the difference?

Precise means all the replicates are close to each other

Accurate means all the replicates are close to the target or true measurement.

I can move a precise, but inaccurate measurement to be more accurate.  I can’t move an accurate but imprecise measurement.
