It's mirroring real life. For example in reality:

F-15C: 940 rounds

MiG-29: 150 rounds

F/A-18F: 578 rounds

Typhoon: 150 rounds

A-10A: 1350 rounds

It's because American aircraft mostly use the M61 Vulcan (and GAU-8 Avenger for the A-10), both of which are gatling guns with ridiculously high rates of fire (6,000 rpm) so they need larger ammunition reserves or their ammo would be gone in a split second. Most Russian and European planes use cannons with lower rates of fire (1,500 rpm-ish).
