I was making some bushings for my Star loader tonight, it has a 1/2" powder slide, the bushings are thus 1/2" od and .495" tall .
anyway I hit on a bushing size that throws BOTH 7.0 Green dot and 10.7 grains of Blue dot. which are both listed as max loads for 158 grain boolit by alliant.
some of the other sizes I checked and made working up to that were giving me the idea that it was going to be close to working out that way.
and according to the Lee manual .88cc of green dot is 7.0 grains, and .88cc of Blue Dot equals 10.8 grains, so that confirms it.
I used a .390 drill but with the nylon bushing in a 3-jaw chuck the hole came out a triangle. will have to try the 1/2" collet next time.
