To reinforce what Ranch Dog has said, with my Auto-disk, I decide on the type of powder and powder charge that I want, using my notes or loading manuals. Then I check the Auto Disk load tables to find the closest (lighter) disk. At that point I run a few charges through to see how close, and in some cases I have used the next one up.
It won't be exact unless you modify the disk, and then you need to make sure it is marked.
