I said 700 was similar to CLAYS , more similar in burn characteristics than size & if ya want a truely tuff metering powder try Unique,Herco or 800x there flakes are twice the size of the 700 in the pic (nice pic Gdawgs , was the camera on macro ??)

A fix for powder drops ,well for most is to cover everything with no.2 pencil graphite.
I have added 1/2 teaspoon to a # of 800x to get it to meter better & it did help with no affect on velocity . As far as adding a bit of graphite goes ,why do ya think most powders base color is gray or black ????

Take some 231 & rub it between ya fingers , that`s rite it`s graphite !!

As far as bridging fix ,I used a flap wheel made from a dowel rod & 400 sandpaper to polish & remove minut burrs from drop tubes then cover with graphite to offer a bit of rust protection.

Also I treat the inside of powder measures with powdered graphite to releive static tension on plastics & smooth the inside painted surfaces a bit .

I have very little trouble droppin accurate loads EXCEPT with Unique !!!
