"....the powder measures by volume instead of weight? Also that it's relatively inconsistent?"
Which measure? Using what for the cavity?
Most volumetric measures I have used are not inconsistent, if one follows good set-up procedures. Personally, I use the Lee Autodisk measures, and with an adjustable charge bar. With the powders I use--typically ball for pistol powders, the typical variation is plus-or-minus one-tenth grain.
RustyFN or others are better qualified to comment on the rifle powders and their measuring techniques. For the limited .223 reloading I've done to date, I use an older aftermarket ACB that works fine with .223--e.g., it produces loads with little or no variation. Since I am just learning the rudiments of rifle reloading workflows and working at the lower end of the recipe, IMO that's fine.
