Francesco, Rumurutiites and Kakangariites are clearly chondritic.
Let's take the LEW 87232 Kakangari-type Antarctic meteorite. The
thin section does show chondrules and chondrule fragments.

As for the R-chondrites, although the lower types have relatively
few chondrules, they do have them. Ouzina (R4) is even said to have
abundant barred olivine and porphyritic chondrules. I don't have any
Ouzina, so I can't tell.

My NWA 3098 slice from Stefan Ralew also shows several chondrules
even though it is an R5.

Best wishes,

Bernd
