I'm working on a list of components for a really light mountain rifle and the barrel keeps tripping me up. What barrels are custom builders using to get a sub 5 pound rifle in stainless? Krieger for example says a minimum #5 for a .30 caliber. If I go with a CM barrel, I can get it down to 2 pounds in a 27 inch tube, but I don't want to risk rust and corrosion in the mountains with a CM barrel if I don't have to. I could get a CM Cerakoted or something, but I'd have to baby it I think.
Here's what I'm pondering for the build:
-300RCM caliber (Close to 3000fps with a 150gr bullet out of a 20" barrel). Might go with a 22" barrel to get a little more speed, but a 20 incher would be great for bushwacking.
- Krieger or Benchmark barrel. Heard good things about Rock Creek, but not familiar with them. (sub 2 pounds if I go with CM)
- Pierce Titanium short action with extra skeletonizing done by them (16oz action and bolt)
- Oregunsmith Pendleton Stock, or possibly send rifle and barrel to Lone Wolf to do (16-18oz stock ideally)
- Jewell Trigger
Any thoughts or advise on how to go stainless barrel safely and get it in the 2 pound range? Proof Barrels have crossed my mind, but I'm not sold on a thick tubed carbon barrel.
