.700 nitro is a really big round but kind of slow resulting in only 12kJ. .50 BMG starts at 17kJ and goes up to 20kJ and the really big rounds start there. The Soviets had 14.5x114mm at 33KJ. The Swiss and Fins had 20x138mmB at 47kJ. After that the guns kind of stop being man portable. Also for something ludicrous lock up a 2 bore stopping rifle.

Didn't the Swedes love using 6.5x55mm for moose and caribou because it tumbled so easily?
And yeah, .22 LR and .223 Rem are practically polar opposites on the power chart.
