Please find me a gunsmith that will rebarrel my Browning that isn't expensive. I have looked and by the time I get a blank, send my action, get it chambered twice I might as well buy a Bighorn Origin and put on prefits. I found McGowen will do it for 220 plus the barrel at 325 plus shipping both ways and a +/-20 week wait. 555+shipping both ways. That's as cheap as I have found and costs more than an ABolt3 and almost as much as some xbolts. You get an xbolt pro at 1,600 and then rebarrel it at another 650 and you are at the cost of some of the customs. Bighorn@850 KRG Bravo 350 TriggerTech 180 Shouldered Prefit barrel 275-550 for stainless....
You rebarrel it again and you are in the red, as you can get prefits that you just put on at home with the customs or even a Tikka. As far as why put an expensive barrel on the Savage...The same reason you would put one on an expensive build. You want a light precision barrel that is stiffer than a pencil barrel so you can pack it up the side of the mountain. That doesn't change with what action you have. Also, I would not buy a Remington and then not have the action trued which means once again...might as well buy a custom. At least that is my thought process.
