No off hand but just google C3 sizing chart and look for the expansion range...then do the same with the C4...

like this one

C4

it looks like C3 #2 is the next one down...

The range of the #2 C3 is contained in the range of the 0.3 C4. However, because of the much narrower head, whenever I carry only one of the two, it's the C3.

The #1 (red) C3 has smaller minimum and maximum expansions than the 0.3 C4.

Actually, I said the opposite. I don't mean to suggest that you should buy the #2 C3 instead of the #1; only that that's more to cams than expansion range. A #2 C3 can often be placed where the 0.3 C4 cannot.

My Yellow C3 is one I place on almost every climb. Fits many more places than the .3 C4.

Guideline #1: Don't be a jerk.
