Tweeners and precision

I've found them to be very repeatable too. I wish Lee would come out with a set of "tweener" cups for greater utility.
You can make a set of such dippers by dribbling a little carpenter's glue, a spitwad or chewing gum in the bottom of the cups. Adjust by trial and error until you get them right. You can also make an adjustable dipper by drilling a hole in the bottom of the cup and installing a machine bolt/screw of a size to completely block the bottom of the cup. The glue is my idea, the screw thing is something I read on another thread. I wish I could remember whose idea it was so I could give credit.)

I use them all the time, they're very convenient for loads that don't require super precision.
What do you use for loads that do require super precision? If you use a powder measure, I suggest you run some comparison tests. If you use a scale for those precision loads, then I agree with you. When I want a precise weight, I dip for a weight just below what I want and trickle up to the desired weight.
Given a consistent dipping technique I would put dippers up against any commonly available powder measure that doesn't involve trickling powder up to weight. Dippers are incapable of jamming, cutting or otherwise damaging powder granules. You also cannot run out of powder without knowing it.
For some folks, getting their dipping technique to be adequate for precision can be challenging.
You do have to make a better chart than Lee provides. It is notorious for reporting light weights, for safety, probably. But if you have a scale, this is easy.
I have owned a couple of different powder throwers and have traded them all off. I now use Lee's Auto-Disk almost exclusively. But if I did not have that, I would just stick a funnel in the powder charging die and use dippers on my Turret press or put a batch of cases in a loading block and use the funnel and dipper to charge.
I know my opinion is not shared by all and I am willing to give evidence for the contrary position a fair hearing, but I have tested my techniques, and for me at least, for their cost, storage space, precision and accuracy (once weight is determined) dippers rule.
Two weak points: Speed and requiring the operator to be more consistent than most mechanical powder measures.
