From video games like Team Apache/Janes/Microprose it seems like the Apache has multiple burst selections. The default is 10 rounds per burst but goes up to 100. Ten seems to work fine. I'm no pilot though. The current loadouts seem fine.

However considering most infantry need 250,000 bullets per kill the land grunts would realistically be leaving the battlefield several times and rearming during a typical scenario it's also plausible to buff up helos the same.
