This thing has metered longshot, trailboss, #7, and 4756 with great consistency.
Today I get some unique and weigh the charges
4.4
4.0
4.8
4.5
4.7
4.2
4.9

Ive seen where folks use a cheap aquarium aerator pump to provide vibration.
Is that my cheapest/easiest option?
thanks

Its not the measure. Just this morning I was throwing 4756
these are very uniform

Yep... I found the same thing.... that why I do not use unique anymore.
I get less than .25 of a grain variance with WIN 231 or HP38 for my pistols out of 100 rounds.

I just drum my fingers on the powder measure for a second before I throw the charge.  Helps a lot.  

Some wise person here said he rubber banded a small feminine vibrator to his powder measure.  Seems like that would work better than an air pump...

Throwing 6.2's

Using a 200 plated xtreme the powder will come awful close to being compressed if I added much more.

Can unique be compressed?
