Need help changing caliber of and firerate of vehicle weapon.

[greywolf-sniper 442624 0]

I'm trying to make the Marshall IFV similar to the real life USMC SuperAV for friend trying to start his unit.
he wants to raise the firerate to 200 rounds per minute, and if possible. put 2 firerates, 100 and 200.
he also want the gun to shoot 30mm instead of 40mm ammunition
Here is my config.cpp for the IFV I'm making so far.

I hope somebody can help.

You'll have to crate a new weapon class or use one that already exists. In case you create a new one, then first make the ammo, followed by the magazine that use that specific ammo type. Lastly for the IFV as mentioned I believe you can script it by referring to the "MainTurret". Have you done this before?

I have, for an IFV it's okay now, but now I wanted to make a tank with ridiculous firerates.

Changing firerates, no mod needed:

this addEventHandler ["Fired",{

  params ["_unit", "", "_muzzle", "", "", "", "", "_gunner"];
   _unit setWeaponReloadingTime [_gunner,_muzzle,0.1];
 }] ;
