    Default Bosvark 5.5mm power test

    Oky the home-built Bosvark by Johan, this air rifle is huge fun, kicks like a mule.
    297cc pressure vessel - Fill pressure 300bar - 24in barrel 1:17 twist (so 34gr should still group but the heavies is just for power )

    First up 18gr 5.5mm JSB full power, kind of disappointing, but seems we need a longer barrel .



    Then we did a 34gr 5.5mm JSB pellet, better, but the Bosvark wants more



    And then for the heavies, 55gr 5.5mm own cast, YEH that's more like it



    Cheers

    Bosvark got an upgrade 820mm 5.5 barrel, photo and video will not be shown because the barrel looks horrible joined two barrels that's all you need to know for now
    Test was once again done with the 55gr pellets at 300bar pressure and the result was 1074fps (141ft/lbs)
