I have the .260 with a 9 and one with an 8 twist. They will both achieve more velocity than the Creed I have with an 8. The 8 twist 260 and the Creed have 24 inch tubes and the 9 twist 260 is a 22". The 9 twist I have (a 700 Titanium) will stabilize 140 SMK and 130 VLD Hunting but not the 142SMK or 140 VLD Hunt. I honestly can see zero difference with the Creed and .260 if both have the 8 twist. I have killed several critters with both and only like the .260 better cause I have hunted with it for an extra decade or so. I do not shoot any factory ammo, but if I did that would give the Creed an edge, and there are maybe a few (a boat load) more rifle options available in the creed. I too also shoot the 6.5x284, 6.5 PRC (my new favorite), and the .264 Win Mag. The Creed and 260 are both easier to shoot, use less powder, and kill stuff under 500 pounds with the same efficiency. You can't go wrong with either. Nosler, Norma, and Lapua all make brass for both.
