50% less wind drift at 1000 yards with 6.5 vs 308.
The ballistics don’t lie. I love my 308s. Don’t get me wrong, I just like the right tool for the job. My buddy the other Sunday shot 2 foot steel with a Springfield Saint 16” barrel, 73gr 223. The target is 1085 yards. He had a three times magnifier and an eotech red dot. He got 2 hits out of ten. One can do it, but it’s not the best tool for the job.
I will likely build a 300 PRC this year, and see how far she will go. I’m limited to 2750 yards off my deck, but if I can get that, I’ll be happy.
That depends upon the bullet. The military tests only showed about a 3rd less wind drift. I have no trouble shooting 1,000 yds with a .308. But, if I need to consistently shoot a mile using anything less than a 50 BMG, I wouldn't be doing it with a Creedmoor. I'd be using a .338. But, that has nothing to do with which one is a better SHTF gun. For now, the Creedmoor loses on that aspect. The 6.5 CM has been around since 2007. Give it some time. It might catch on this go-round and become widely used enough that ammo and guns for it will be plentiful, varied, and cheap. But, the one thing it has against it compared to a .308 is short barrel life. That's likely what turned people against it when it was first introduced.
