Any tips on throwing small charges on the ATV3? Or can you?

Loading some 357 Mag subs and tried to throw 6-11 gr of Unique or H110.
The AT main throw won't go that low so I tried to use just the trickler. Very slow.
Do you adjust the angle of the trickler down to the cup to get a faster charge?
It was getting late and I didn't try the angle change yet.
Ended up using the Chargemaster because I needed to get finished.
 
You can adjust the angle of the tube and the speed of the trickler for the last 1-1/2 grain. You can also play around with different insets in the end of the tube. But if you want good repeatability it won’t be very fast with powders like Unique.

I use the Lee dippers to throw a small charge with my V3 unit. For example, I use 4.4gr of TiteGroup for a .38spl load for my revolvers. The Autothrow on the V3 would never throw a charge that small. So the small dipper throws approximately 3.75gr, and the Auto Trickler does the rest. It works very well for me. I also do it the same way for other small charges such as 6.0gr, 7.0gr, etc. (just with larger dipper scoops).
