I've been using a Redding Bench Rest measure.It's really accurate with ball powders and the longer the extruded powders grain is,the less accurate it is.Also,it starts to fluctuate more as the level of powder goes down.This along with case prep,is the most tedious part of reloading.I just got a Hornady Auto Charge dispenser.Grafs has them on sale right now for $186.00.After looking at some Youtube reviews,I liked what I saw and placed my order.I like to weigh each charge and this thing is right on the money.When you figure the thing is a powder measure,scale and trickler,the price really isn't that bad and sure saves a lot of time too.
