Thread: Ft/Lbs Legality of Power Drop-off at Range

  1. #1

    Ft/Lbs Legality of Power Drop-off at Range

    If I shoot a round that (at the muzzle) generates 1750ft/lb and flys at 2450fps with a 150grain bullet then it is legal for all deer in Scotland with a 50 grain margin of error.

    If the deer is at 300 metres and the chart for that rifle/ammo combo says at 300m there is 1500ft/lb...is that shot legal or illegal?

    The law is about muzzle energy not what the energy is at any other distance , obviously bullet weight stays the same regardless of distance.

    Cool, that makes my calibre choice easier as I was worried the 6.5x55 might not be legal on Scottish Reds over 150m.

    Thanks.

    Nothing wrong with that choice

    Sounds like a .30/30 then?

    Where a minimum energy level is required for a rifle to be used legally against a particular species, as far as I am aware, the law states that the energy level shall be measured at the muzzle.
    Anything else would be unworkable.

    In Switzerland, the energy is measured at 200m and if I remember correctly it has to be 2000 Joules at 200m.

    ft/lb isn't a unit of energy - see http://en.wikipedia.org/wiki/Foot-pound_(energy) Regards JCS

    Why not?
    "The foot-pound is often used to specify the muzzle energy of a bullet in small arms ballistics, particularly in the United States."
    Or have I missed something obvious?

    Toxster wrote ft/lb which isn't an Imperial unit, ft-lb is. Regards JCS
