RE: powder mesure
RCBS beam scale and screwtop clear vials to store,is what I use. I still have a clear volume measuring device to find the intial charge, then weigh and duplicate for vials. Garage sale dot stickers works well to place on the cap to let you know the load at a glance. Works well for me.
I personally never liked the brass volume measurer's, due not being able to see how the pack is with the pour from the keg or flask. I prefer larger vs long and lean.
