Is that suppose to mean something, That’s been done with many calibers and long before the mediocre Creedmoor became popular. The 26 Nosler and my 6.5 300 Weatherby out runs it by about 500 ft/s. At 400 yards I’m still running faster than the Creedmoor at the muzzle.
Now if ya got a bad case of sissy shoulder then by all means shoot the Creedmoor, that and it’s ability to be run in a AR-10 frame size is the only real purpose it serves.
You just put your finger on it. Ammunition optimization for the AR10 platform. That's where it shines.
For no recoil, and precision, it’s hard to beat the creedmoor package, they did a great job on that one. Also, it’s cheaper to shoot than some others. If I need more than that for range, I’d go build a 300 Norma or so, maybe a 300 PRC (still watching that). Load the bullet further up the neck of the case. It’s not always about speed either. Actually the whole subject is very complicated and there are so many variables that I’m sure you’re aware of. To go and bash a cartridge because you don’t like it seems silly.
I do love my 308s too, but they serve a different purpose.
