Vulcan (cannon) question.

Hey, guys. Happy New Year.

Two questions concering the M61A1/A2 Vulcan cannon.

One, are there any minimum/maximum airspeed limitations when firing it?

And two, are there any minimum/maximum G limitations when firing it?

I know that older gun systems would often jam if fired under negative-G, due to improper ammo feeding, but I was thinking that issue may have been addressed in the Vulcan design. But then again, it’s about a 50 year old design, so…
