I did the custom rifle a few years back, but in 6.5 PRC.
Of those listed I would go 7PRC.
I used a Defiance anti X action, with a proof carbon barrel, and XLR magnesium chassis. I have also since build, "put" together a bench rifle 6.5CM to practice with. The 6.5 CM is off a Cadex action, with a heavy stainless IBI barrel, again sitting in the XLR chassis.
I would not hesitate to order any decent action, and there are lots of them to choose from. Bighorn, Defiance, Falknor, Cadex, among others will all be built as "prefit" to very tight tolerances. Basically pick the $$ to weight ratio you want and go from there, as there are plenty of great actions.
I went IBI barrel with the bench rifle, just because they use the "savage" type mounting system allowing me to mount, or remove the barrel easily at home without having to get an action vise/wrench. Just unnecessary costs. With everything "prefit", I had no problems putting the action and barrel together at home, and even set the action a bit tighter than the go gauge, just because I could. This just makes it not necessary to have the tips protrude far out of the case while reloading, plus less initial brass stretch at first firing. I shoot out to our range max at just under 1400 M with this rifle, so I know something is right.
Very easy to put together prefit rifles at home with some basic knowledge and caution. I had purchased 500 rounds of factory ammo to shoot through this new rifle when built, and set up the barrel to just allow this, so I know its less than the SAMMI spec, and I'm okay with that.
As for carbon barrels, I would not hesitate to use one on a hunting rifle and I'll continue to do so. I will easy get 5 rounds down range before things heat up and don't have to wait between each shot for cool down on the pencil contours. I've used kimber adirondach rifles before for the wife, so know how the pencil barrels heat up with each shot. My IBI bench rifle sees me shooting 50 round strings when I go to the range, but that's another story.
If I was looking for a new stock I would seriously be looking at the new MDT carbon stock that just came out. Me I like my chassis, so will be sticking to it.
