On the first of the two flights, the pilot destroyed eight Russian drones, firing 400 rounds from the F-16’s 20mm M61A1 Vulcan cannon and landing with 100 to spare, the wing said. Days later, he went up again and broke his own record, downing nine and returning with 80 rounds still in the belt.

The M61A1 fires 6,000 rounds per minute, so that's about a half-second long burst per target.
