Actually Clay Dot has orange dots, and is a little cheaper than Red Dot. It's supposed to be as clean as Clays, and although they don't say you can use Clays loading data, if you look at the published data, its pretty much the same. Promo has no dots, is quite a bit cheaper than Red Dot and uses the same loading data as Red Dot. Important note: Same weight as Red Dot, not the same volume!
