Who builds 6.5 PRC OTHER THAN GAP OR SAC?

It's not really a "build" but if you have an AIAX-MC you can get a 6.5 PRC bbl easy peasy - just call MHSA with your credit card handy. Think you need the LA version? Not sure...
It'll fit into a short action AI style magazine if you use one without a binder plate, but only just barely. It's a no-go for standard magazines with binder plates though.
 
Go with PVA this is my 1k group with my hand load

Is long action or short action the way to go on these?
Depends. If you only ever plan to shoot factory ammo from Hornady a short action will work just fine since the ELD-M offering from Hornady is 2.95" COAL and their ELD-X is 2.945" COAL (AI mags with no binder plate can fit up to 2.95" rounds).

If you want to hand load it would be best to either get the gunsmith to chamber the throat a bit shorter so you have more wiggle room for bullet loading, or just build on a medium or long action.
 
MPA has them as well. I picked one up off the rack from Xtreme Guns and Ammo.

Throated for the 147. Going to try to shorten the COAL on my handloads to 2.89 for a Ruger AI mag that I obtained to see if I still get the good groups and ED/SD with RL26. May try pushing some factory down also.
 
I've been really impressed with this round so far. I've built a handful of them and with the reamer I'm using, factory Hornady ELD M has been shooting well under 1/2". The last rifle I built will be heading to Colorado for elk in a few weeks. My customer called me back a few days ago and told me he shot a 3 round group using the Hornady eldX at 300y and could cover it with a dime.
 
what is a binder plate
It's an extra plate on the inside of the front of the magazine, at the seam where the magazine is welded together. It reduced the room for long cartridges inside the magazine by a fairly substantial amount. The intended purpose of it is to make the magazine more durable, but I personally haven't seen or heard of magazines without binder plates failing at the weld before.

You can see it at the front of the magazine there, the rectangular piece up against the front of the magazine between the mag body and the follower. It's just a piece of metal that runs the entire length of the magazine, meaning you can't run as long of bullets inside the magazine because the binder plate takes up space.

There's a photo of the magazine I use most often, which is an AICS pattern magazine with no binder plate (made by Accurate Mag). As you can see my follower in the spacer kit I use is able to go all the way up to the magazine body since I don't have a binder plate in this magazine.
