I am wanting to build a lightweight long-range 7mm Rem Mag out of a 110 action to shoot 180 Bergers. I am currently packing a 110 action in 300 WM with a 26" McGowan barrel, Gentry brake, Duramaxx stock, Harris 6-9 bipod, NXS 5.5-22x56, NF rings and an EGW 20 MOA picatinny rail. The thing shoots great out to 1000 yards but is a little heavy to pack.

Any thoughts on a barrel contour that will be rigid enough but lighter than this Varmint contour? I am going to use a lighter scope, probably an older 4.5-14x50 Leupold tactical and a lighter base. Whatever barrel I end up using will get fluted. I'd like to stay around 27" with brake. What about the stock? Any other places to drop weight?

Thanks for your thoughts.
