    Very Interesting.
    Here is another of his links - http://www.dave-cushman.net/shot/tkochart.html

    Many years ago, I became interested in calculating energy. Not so much now. Pretty much, it gets the job done or it doesn't.
    Here is another link on Kinetic Energy. http://en.wikipedia.org/wiki/Muzzle_energy
    I guess we payed someone to come up with this stuff. Not sure how they came up with the E=1/2MV squared idea.

    I concluded at that time to leave out the whole "squared' thing and base energy solely on weight & velocity.
    I figure it's like hitting a brick wall with a Half Ton Truck at 45 mph vs a VW at 90 mph. Which does the most damage. Better yet, which one achieved the predetermined goal?
    What caused me to question the whole KE thing was when "someone" claimed that the 9 mm Luger had energy equal to the 45 acp. :confused: :confused:
    Then came the debate about the 17 HMR vs the 22 Mag. :confused: :confused:
    Back to my original thought, "does it get the job done?"
    But I guess it doesn't hurt to have a reference to establish a starting point and adjust from there based on experience.
    Or, just ask one of the members on the Marlinforum. We'll help get ya started.
