I have a suggestion for you, as a lot depends on how you use them.
Take a flask and measure out 10 loads then weigh them on a powder scale- then get a good top leveling powder measure and weigh those to. The one that is the most consistant is the one you want; I quit using a flask about 10 years age after I did this my flask numbers were not so good and just pouring loose into a good clip the top measure was a lot more consistant for me and since you should not pour from a flask directly in to the barrel any way .
