Extruded powders are difficult in a lot of the drum type measures, but supposedley fixed with the Quick Measure. I actually have on of the Quick Measures, and haven't had it long enough to even set up and use.
Honestly, the best measure I have found for extruded powders is the el cheapo Lee Perfect measure. I have set it up against both Lyman and RCBS drops, and it is consistently more accurate. So much so, that I actually have two set up on my bench. Do yourself a favor and pick on up, they can be had for under $20. Believe me, you will be impressed with its performance.
