Avoid parts from colliding if they have the same name

  1. What do you want to achieve?
    I am making a fast firing weapon, a minigun.

  2. What is the issue?
    The bullets keep colliding with eachother and destroy themselves.

  3. What solutions have you tried so far?
    I have seen collision filtering and no collision constraints, however they are constraints and putting them individually into the bullets would be tideous and will consume resources.

Any kind of help would be appreciated.
