    velocity x velocity x bullet weight then divide by 450240 = ftlbs

    Not enough info! It's no use without defining the units! Please do confirm!

    Velocity in ft/sec ?

    Bullet weight in Grains ?

    What calibre? If a factory loading in that calibre meets the minimum legal requirements of diametre and energy thats all you need to know.

    Thanks for the help guys. Basically what it is, I have an 18in barrel 6.5/47 that I shoot 100grain bullet with and I was thinking of using something heavier but due to the loss of mv caused by my stubby barrel I wanted to work thing out to stay on the right side of plod.
    Regards

    Jimmy 6.5x47 with a 100g bullet or more will easily be okay, the police have neither the time or the resources to go about examining bullets retrieved from shot beasts or chronographing your handloads to see if they meet minimum specs, factory ballistic data tells them all they need to know.

    Thanks but like I said I was wanting to go heavier and slow things down so I get less hydro damage, I was thinking of chronographing some 140 out of my stubby tube then trying to work it out.
    get ya point regards police resources but just for my own piece of mind and all that, plus I just like to know for knowing sake.
    Regards

    Ian I am surprised that the Scots boys haven't jumped on you yet, you forgot to mention the minimum velocity requirements north of the border.
    It's the calibre of the shooter that counts not the calibre of the rifle.
