"Does anyone have a measure that throws consistently with Unique?"
I've have good luck using my Uniflow for throwing charges of Unique. dunno if it's just a case of good luck or I I just hold the handle the right way. I have three Uniflows ( don't ask) and the other two won't throw Unique worth schidt. Go figure. I use them for handgun loads only with the exception for the .223 Rem. with ball powder..
For rifle cartridges I use the RCBS Chargemaster or Chargemaster Lite. They make resetting for the next charge simple during load work ups. I find them too slow for charging handgun rounds though.

Unique has always been a problem for me when using a measure. I have an old RCBS Uniflow that's a million years old. It didn't work with some powders despite my efforts to tweak it.
I am going to try a Lee Auto Drum and see if it works. They are $50 CDN.
