On the metering .. Seems to be a popular topic with the shortage of certain powders or people finding good deals somewhere but have trouble getting it to throw consistently.
I use a Redding BR3 or BR30 measure with the RIFLE micrometer measuring tube in it ..
You have to adjust it pretty low, however, the disc / surface area is larger with a shorter depth to hold the powder so the flakes are less apt to stick or bridge in the measure tube ..
The smallest amount I can throw is 0.8 gr.
You still need to drop the charge slower than most and tap the handle once you drop the charge.
Doing this way I have been able to throw 6.0 gr charges for my 9mm 124 Gr RN all day with no need to trickle charge ..
At the range, the velocity spread for 5 rounds was 8 fps ..
Hope this is helpful, seems to be working okay for me ..
