I load a lot of calibers and a lot of different loads, so keeping my powder thrower in the same place, or even trying to record where the adjuster is at would take too much time. So last night, I was loading, and found a little trick.
First, weigh out the charge you are going to throw, and put only that into your powder thrower. Make sure the adjustment screw is out further than the load is large. After getting all the powder you can down into the measuring cylinder, just turn the adjustment screw until the powder has come to the top of the cylinder. That should be just about the right adjustment, and then fill your hopper and throw charges to make the final small adjustments.
Something I noticed that saved me some time... hope this helps.
