    Powder\\Velocity\\Accuracy

    Why can two powders, pushing the same bullet at the same velocity have such varying levels of accuracy? I don't question that it's true, but why? /ubbthreads/images/graemlins/confused.gif

    Differing peak pressures, bullet acceleration and barrel harmonics.

    That's my uneducated guess. /ubbthreads/images/graemlins/smile.gif

    I would stress barrel harmonics. Different Rifles of the same make, and same cartridge will shoot the same bullets differently. That is my uneducated guess!
