Fair warning I skimmed through the replies so I'm not sure if this was already said.
With the current offerings I cannot wrap my head around 6.5 PRC.
You are hamstrung as far as factory ammo goes to Hornady, Federal and I think Nosler has something coming(not a bad option but you're going to pay handsomely).
As of right now for brass I think there is Hornady, ADG (good luck getting your hands on some), Nosler and I think I heard Norma has some coming too (probably where Nosler's is coming from).
So out of those options for brass you're hoping you can act swift enough to actually get some ADG, if not try to chase down Nosler/Norma otherwise you are stuck with Hornady or Federal. I don't know if I am alone in my opinion here but IMO Hornady and Federal are such poor options for brass that I will not use them. I've never seen cases lose primer pockets as fast as Federal brass, absolute junk.
And then if you actually analyze the velocity differences, you're not gaining very much by going to a PRC. I believe the difference in speed of factory Hornady Precision hunter is under 300 fps, closer to 250. Couple that with the loss in barrel life, Dave Emary himself estimates PRC barrel life to be in the 1400-1500 rd range. The Creed is widely considered to be a 2000-3000 rd barrel. I don't know if I want to sacrifice almost 50% barrel life to gain a couple hundred FPS.
You can open this argument up even more if you start comparing 6.5 creeds loaded with RL26, there are guys breaking 3000 FPS with 147 ELDs. I don't think the PRC is really pushing anything much faster than that and it's still taking more powder to do it.
This is all just my opinion but based on the multitude of factors, I think 6.5 Creed will outlive PRC.
