Has anyone tried one of these, or seen one work??

I have one and it works very well.
I would say a little better than my Harrells and a whole lot better than an RCBS Uniflow.

rcasto: Thanks, I am considering getting one; and you are one of the few who has actually tried it. The design of the Quick Measure looks pretty slick. Have you weighed a few charges thrown by the Quick Measure to see what variation you get (high to low)?

Variation is about .2 gr on average. The trick, as in all measures is to be consistant in how you throw the powder.

I should probably add this. The Quick Measure is well made and functions smoothly and measures powder about as accurate as one could expect. Is it as accurate as the manufacturer suggest? - No. But no measure is. If you already have a high end measure (ie Harrells or others) you probably don't need this measure. If you are looking for a higher end measure this will work very well for you.

racasto thanks, This is just the kind of info I was hopeing for. I`ve a old Lyman that works OK with ball powders but doesn`t work as well as I`d like with stick. I think I`ll try one of the Quick measures.
