If you reload the 6.5 Creed easily does 2950 with 140 class bullets. Just have to find some rl-26. If your only shooting to 300 yards just about any cartridge will do it for ya. I'm kind of biased on the 6.5 Creed because I use it for 1000 yard compatition. It does really good at long range. If you don't reload go with the 6.5 Creed anyway. Hard to find a more accurate rifle with factory ammo than the 6.5 Creed. They all seem to shoot so good. Killed my biggest buck ever with a 308 but it's just plain boring. Good round but boring none the less. Energy levels are very similar at 300 yards but the section density of the 6.5 bullets are very high. Here is a little comparison for you to think about. A 308 with a 168 Berger vld doing 2800fps will have 1200 ft pounds to 585 yards. The 6.5 Creed with a 144 Berger at 2850 has 1200 ft pounds to 780 yards. That's almost 200 more yards with the same energy. And at 585 yards the little Creed has 1480 ft pounds. At 300 yards the Creed has 100 more ft pounds than the 308. These numbers are easily verified in any ballistic program. I happen to use Shooter. Someone is going to say run a 175vld at 2700 and see. It's the same numbers as the 168 at 2800. The math doesn't lie. Wind drift numbers between the 2 are only close at 300, beyond that and the Creed easily out paces the 308. Did I mention less recoil in the Creed also. But remember I am a biased 6.5 supporter. Just look at the math yourself.
