I'm in the process of building a 338 Norma. Right now i have a Brux Rem Varmint barrel 26" Interrupted fluting. And I am going to order another Brux barrel but lighter than the one i have know.I am trying to build this rifle somewhere around nine to ten 1/2 pounds.I also want this rifle for hunting and target shooting.I know heavier barrels are more accurate but i want it lighter than my 300 rum its 13.5 lb.with a Rem Varmint barrel.So my question is what barrel contour would you go with to go lighter.
