For those looking for a fast powder measure that accurately measures all powders including those of the long stick variety, the Quick-Measure is supposed to fill the bill. It operates similar to a B&M, but the interchangeable drop-tube is attached to the measure and spring-loaded. The load rate is something like 100-rounds in a little over 4-minutes.
Here is mine mounted on the bench. I haven't used it yet, but plan to load lods of 7.62mm and 30-06 shortly and will report on it speed and accuracy.
