Never came close to getting 3000fps out of a creedmoor like I can do with the 6.5-284. In fact 2800 was all I could get out of the creedmoor in a long range hunter 26" barrel with H4350. 57.5 grains of Retumbo in the 284 and the weather warrior with its 24" barrel will give you 2950 with room for more. All depends what you want to do with the rifle. If for hunting I choose the 284. Strictly paper the 260 or creed will work great.
