Uncle Billy,

Just FYI, Unique is known far and wide as the hardest powder to meter consistently from a powder measure. Lee says flat out that their Perfect measure won't work with it. The big flakes bridge across the entry to the powder metering chamber and stop it from filling completely. Some people add a vibrator to the powder measure to help break that up, though I haven't tried it personally. You have to be careful you don't vibrate so much you pack the metering chamber too tightly for the measure to operate. Only ball powders seem able to meter within .1 grains consistently.

Skydiver3346,

That ship may have sailed already. The OP is from late February.
