Relative was a WWII pilot flying P-38's. Basically when they straffed the islands the soldiers below would be blown into pieces. Very powerful round and to compare to a "scaled up" .30-06 is ridiculous.
But the P-38's concentrated firepower didn't suffer from pattern convergence, and so soldiers were likely hit with multiple rounds, along with a 20mm cannon round at intervals which was also part of the Lightning's armament. A bit different than getting hit with a single round fired from a rifle, though I'm not detracting from the .50's awesome power.
