He could if that's all that remained in the system.
You make a lot of sense -- I know it takes about a half second for the Vulcan to reach it's full fire rate, so I'd guess it would fire 55-65 rounds in the first 1 second of shooting. But, I agree and still don't see somebody being able to squeeze off just 25 rounds?
I know this hardly constitutes an Accident Investigation Board, but do you think that considering the 7000' altitude (which does seem too high) the pilot may have been heading in and when he switched the Master Arm on OR selected his gun, that might have triggered some sort of electrical short in the firing circuit?
Just thinking out loud?
