22 inch barrel ballistics

  1. .270 ballistics - 22-inch barrel

    Rifles and Rifle Cartridges
    Ballistic charts usually give data for .270 win for a 24 inch barrel (i.e. 3060 ft/s at the muzzle for a 130 grian bullet). What average velocity, and trajectory shall I expect for the same commercial loads at different distances shot from a 22 inch barrel?
