Make a certain ammo take the effect of another

[Albalrogue]

Hi,

 

I'm wanting to create a mod that will add a new kind of .50MG ammo (for the anti-material riffle) that has the same effect, damage wise and animation wis, as a mininuke.

I want it to keep the bullet model so I created a new .50MG ammo kind but I don't know how to give it the mininuke effect.

 

Can you explain to me how to do so? I'm new to modding.
