However .30 would still be well within the maximum load, right?
Yes that is correct.

No idea what I should do with this,
It is used to determine which disk opening to use, if you wanted to load 3.5 grains of W-231 you would multiply 3.5 X 0.0931 = 0.33 to get that information. But since there is no .33 opening in the disks you would need to use .34 opening to get close to 3.5 grains charge.

so just set the disk up for .30 and go for it! Too simple?
Yep, why make life more complicated?

I would think a .38 special wouldn't be the tiniest load possible
Actually, it isn't the tiniest, using the adjustable charge bar which Brian suggested, you could get even a smaller charge of powder, not saying you should but you could.

I use 4.7 grains of Win-231 for my 38 specials (125 grain bullet). But I use the adjustable charge bar for dialing in the charge on a Auto Disk powder measure, you would need to use the opening of .46 on your disk, yes I know it says 4.9 grains on the chart, but the disks very seldom if ever give the exact throw as the chart states.
