First, if you can't get Unique to meter, you need a better measure IMO. It runs to 0.1gr accuracy in my old Duo & Dillons. Any ball or spherical pwoder will meter smoothly & accurately. If you liked the burn rate of Unique but can't get you measure to run well (Lee is a good example) then try WSF. Almost identical burn rate & meters a bit better than Unique. AA#5 is even better, but I am not 100% sold on it vs WSF. TG makes lovely fertilizer.
