Tin Star and Trail Boss are your only viable options.

I understand your concern--it was quite an adjustment switching back .38 Spl after spending a lot of time loading 9mm and being able to see the case fill easily. All of a sudden, those big tall .38s seemed awful risky compared to the short little 9s. But I think that you're really limiting yourself in powder selection, and that it's just not worth it. Especially with a single-stage press. Even though you have the sort of "different" risk of double-charging, it's a lot easier to check each case before seating each bullet than it is on a turret or a progressive.

Perhaps instead of looking for volume, it might give you peace of mind to try a powder that's lighter in color? Winchester SuperTarget, for instance, is very light gray-green in color, and is very easy to see in a case.
