It's 20mm, not 25mm.....A minigun made of the Bushmaster rounds would be quite nice though, but the RPM on the 20mm is nice, 2000 to 6000 RPM depending on your settings.

It's 20mm on the AC-130H Spectre, but it is 25mm on the AC130U Spooky. From above, the 25mm round is efective against all armour.

My husband has seen the AC-130 and his comments were that he would definitely NOT want to be on the ground when that plane came at you.

Yeah, no sh*t. That thing could put 200 rounds dead-center in your chest before you hit the ground.
