This meteorite (Nwa 3098) looks a lot like some material I have...NWA 1774.
NWA 1774 R3.8 - 6 (not R5) 714 g TKW Found 2002
I have some NWA 1774 and a thin section for sale if anyone is interested.

G'day Bernd & Francesco,
Ah yes. What a beauty NWA 3098 is! It is also this month's favourite at my

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
