[Terminator 2] Instead of using the minigun against police cars what if they saved it for the T-1000?

How effective would it be? Would it be able to keep the t-1000 from forming back together?

The whole point of the T-1000 is that it's ultimately impervious to projectile weapons.

Punching holes in it slows it down marginally.  Big holes slow it down more, small holes less so.  What the minigun does is punch a lot of small holes very rapidly. 

Best case scenario is that they can use it to break the T-1000 into very small parts for as long as they have ammo.  After the ammo runs out, it more or less instantly reforms.

At the end of the day, it's not an effective weapon against the T-1000 and it was a good tactical decision to use it against the police instead.
