The 56 grain load gives 4761 foot pounds of energy I calculate.
Sample loads for momentum comparison:
730 grains at 1714 fps >>> 4761 ft-lbs KE <<< 179 lbs-fps Momentum (WFN cast-bullet freight train will be hard to stop.)
Compare to Sir Jerry's .458 WM+ TBSS from a 24"-barreled .458 WM M70 with 3.545" COL, 83.0 gr AA-2460, WW brass/F215:
500 grains at 2368 fps >>> 6225 ft-lbs KE <<< 169 lbs-fps Momentum (Quite the penetrator too, no doubt.)
400-grainer at 2122 fps >>> 4000 ft-lbs KE <<< 121 lbs-fps Momentum 500-grainer at 2122 fps >>> 5000 ft-lbs KE <<< 152 lbs-fps Mo' Momentum 600-grainer at 2122 fps >>> 6000 ft-lbs KE <<< 182 lbs-fps Most Momentum
Other favorites: 400-grainer at 2627 fps >>> 6129 ft-lbs KE <<< 150 lbs-fps Mo 400-grainer at 2599 fps >>> 6000 ft-lbs KE <<< 149 lbs-fps Mo 400-grainer at 2500 fps >>> 5551 ft-lbs KE <<< 143 lbs-fps Mo 400-grainer at 2400 fps >>> 5116 ft-lbs KE <<< 137 lbs-fps Mo 400-grainer at 2373 fps >>> 5000 ft-lbs KE <<< 136 lbs-fps Mo
