    On paper which should have more recoil. the weatherby load is the max according the VV reloading manua for an 87 grain bullet and N150 Powder. The .308 load is one that an aquaintance at an f class match shoots.

    .308 winchester
    N150 44.9 grains
    174 grain BT FMJ
    Lapua brass trimmed to 2.008
    large rifle primer
    COAL 2.83

    .240 weatherby magnum
    N150-44.9 grains
    87 Barns tipped tripple shock

    Norma brass trimmed to 2.448
    large rifle magnum primer
    COAL unkown

    Which one will recoil the most

    I did a little guessing since rifle weight and bullet speed wasn't given.
    I assumed 9 lbs and 3500fps for the 240 WBY & 11 lbs and 2650 fps for the 308 WIN.
    My program gave the following.
    240 WBY 8.3 ft/lbs recoil at 7.7 fps
    308 WIN 11.8 ft/lbs at 8.3fps

    So the answer is the 308 recoils harder and faster.
