10000 Joules (j) = 7,376 Foot-Pound Force (ft lbf)
The only cartridges which push over 10,000 joules of muzzle energy are Anti-Tank rounds, Heavy Machine Gun Rounds, and Elephant Gun Rounds.
Gosh there goes my plan to use a .458. No wait that only makes 7235J. My 600 Nitro Express could still be an option if I keep the 900 gr (58 g) bullet under 1,950 ft/s (590 m/s) because that load produces 7,600 ft⋅lbf (10,300 J). But the
900 gr (58 g) bullet at 1,850 ft/s (560 m/s) 6,840 ft⋅lbf (9,270 J). Talk about a law which has no real value except to make the uninformed think you are doing something. 50BMG is out unless you can load it down. Wonder if he had a 600Nitro Express or was just using a legal gun as a prop?
