They are as good as it gets. How good depends on the type of powder plus the operators skill and consistancy. NO volume measurement of chunky items can possibly achieve totally consistant weights.
How much of anything will go into a bucket depends on how well the stuff arranges itself as it enters. Like, how many tollet tissue cardboard cores will fit in the bucket will depend on how they lay. Carefully place them in rows and layers and you will get a certain number. Just dump them in the bucket like a powder measure has to do it and you'll get significantly less and it will vary considerably.
Absolute precision of powder charges in properly develped loads is a lot less important than many seem to think. </div></div>
I would take issue with that. They are a volumetric measurement, not a weight measurement. If all comes down to how accurate do you want to be able to throw and with what powder. They do well, they are not the end all, be all for accuracy though.
Go back to stoichiometric chemistry; balanced reactions are measured in mol of reactant and product, not volume.
