I have been holding off on getting a Creedmoor caliber rifle. I think I want one, but I have enough on my plate perfecting my long range shooting, DOPE data collection, and reloading of my other large caliber rifles.
At some point I will probably get one. I know its improved over .308, but with a .308, 300 Win Mag and a .338 Lapua available, I am not sure what I would gain by it other than more bragging rights at the range.
Was thinking a .224 Valkyrie.
Whether or not the 6.5 Creedmoor will "outperform" the 30 cals is a matter of specifics. You can definitely shoot some of the newer .308 bullets out there that will give you better performance. There are many factors to consider, one being that 6.5 Creedmoor barrel life isn't nearly what a .308 Winchester is.
I already have a 6.5mm firearm. It’s called a Beretta Model 950 .25 cal. Not quite the same velocity or range, but a 6.5 nonetheless. Just my $.02.
