The
JDS Quick Measure normally stays within 0.2 grains with stick powder. I have both that and a Redding 30BR that does not do as well with stick. The Quick Measure can be adapted to the Dillon presses. Otherwise, it dispenses powder through special funnels that have to be used with it to close the metering chamber at the bottom. Works as advertised for me. Better than my Dad's Harrell with long sticks, like 4064.
Be aware that many stick powders are affected as to burn rate by packing density, and this is why volumetric dispensing of them often works well despite some weight irregularity. But with the Quick Measure gives you both weight and volume consistency.
The next best stick measure, in my experience, is the inexpensive Lee Perfect measure. However, I have two, and one works better than the other. So there's some catch-as-catch-can involved with it.
