Gatling guns go through more bullets since those builds are more about speed. Rifles are about big, single-hit damage over long ranges so they use the least amount of bullets. Shotguns and grenade launchers lean more towards big AOE damage so they consume less than gatling guns, but still more than rifles. Pistols go through bullets a little less than gatling guns.
I'm experimenting with a shotgun build and it's really dependent on skill usage to do good damage, so you'd need to either have a big SP pool or a lot of SP pots. Not to mention a Dark Blinder is a must if you spam Full Buster since that skill had a chance to blind you and it gets pretty annoying fast.
