My head hurts reading this thread...
But I'll still put in my opinion...the Creed is nothing new, it's over a decade old. The only reasons it's popular is because Hornady is great at marketing, cheap "good" ammo, and the velocity restrictions in the PRS.
For a cheap to shoot plinker/target rifle they fill a niche.
For a hunting rifle, velocity kills and the Creed is pretty weak.
