Interesting question Pb, but with modern electronic sighting backed up by holographic sighting I doubt that the elevation/azimuth of the gun really matters too much in the scheme of things.
Fiction Pb - the gun was all about 'self defense' not strafing. The wild weasels were only F-105s in flak suppression and the 105s had the most migs (and losses) until the F-4 took the lead in 1971 - all M-61 kills.
When I flew the A-10c simulator back in April, the HUD gunsight computes Point if impact at any range.. the F-105 had similat comptation in the gunsight but two generations behind th A-10 systems.
The specific F-105 that Syscom put up there was the only F-105 that killed three Migs..(two different pilots) - don't know if any specific F-4 or F-8 shot down as many
The F-4D that Steve Ritchie flew on his 1st and 5th kills wound up with total of 6 kills for the war. It is on display at the Air Force Academy with six red stars on the splitter plate.
