Talked to federal engineer (not salesman) at Shot as well as RCBS and Seekins rifles. Very interesting, rcbs will have dies soon (neck size ) and Seekins is swapping their entire rifle line over to new design bolt and action for these types of cartridges. The new Seekins is really cool 3 lug 60 degree throw. Easy barrel swap design. I believe tool less takedown on bolt. 
the cases don’t show movement in the body after firing so neck size is all that’s needed. (No data on case life) 

round prefers a 5 groove bore at 1:8

Less powder is expected to equate to decent barrel life  

ammo is now available ( recieved 20 boxes 175 terminal)msrp 59.99

Even more fun, 338 ARC

I'd love to get some trigger time if you do a build.
