Some advice for TR Heavy Assault...

[MorpheusX]

Hey guys, just a quick question. When using heavy assault as TR (chaingun), is it worth it to carry both types of ammo? Switch to AP for MAX's and use regular for infantry? or is it more worth it to just go all out AP since the rate of fire is so high that generally speaking even AP bullets should still mow through infantry? I've been trying to decide because currently my loadout is 200 normal bullets and 100 AP, but when I switch to AP to try to take out a MAX, that one clip goes REALLY fast. Any advice would be appreciated.
