It is my experience that the barrels that shoot well with the Harvester short black like the MMO HPH24 for bullets that don't shoot well with the short black. Mine also shoots the regular green, it takes a tighter barrel for the Crush Ribs, I used to use them before I lapped my barrels.
Unless you have an abnormally large barrel for a TC the Red Crush Ribs are over sized, I have some laying around that wont shoot in ant of my guns not even the Knight.
I like loads over 100grs and it seems to me that if you use heavy loads the bullets that are closer to bore size are more consistant groupers. Lee
