As for its use on helis and the LAV-25, the GAU-8 magazine is huge. Its ammo size/bulk would require much larger gun turrets and/or take up a lot more internal space. If the A-10 is built around the GAU-8, a heli or AFV would have to as well. The ability to carry more ammo is probably why the U.S. armed forces prefer 25mm to 30mm.

Please read again. I was speaking about the 30mm round being adapted to other equipment not the GAU-8

The Giant Ass Unit is as you say, too large. However the round used in a single barrel cannon like an enlarged M242 would up gun other platforms considerably.
