To go serious for a moment, I'm always amazed at how LITTLE ammunition fighters carry. That 47 rounds equates to about 12 seconds of firing. Yes, you carry extra drums, but there's no way you're going to change them in combat. And the P-51D had six .50 cal machine guns, each loaded with 400 rounds, and each gun shooting at 800 rounds per minute. How'd you like to fly to Berlin and back in 1944 with only 30 seconds of firing time?
