    do you think i would see any velocity increase in a 260 rem vs. 260 rem improved in a 20" barrel?

    I guess roughly 47fps..
    But why would you go with such a short barrel for such a large cartridge?
    Your gonna get a great big ole high pressure/high flow fireball at the muzzle, which don't contribute to clean bullet release.

    thinking of buying a savage 11 lightweight hunter in 260 rem. also thinking about buying the lightweight hunter and making it into a 7WSM with about the same contour barrel fluted and 24" long. mountain carry rifle i guess.
