The same macro for a double hit, only with endless rounds in the clip, does a QQ after each double hit. Set the macro to any button convenient for you. For the macro to work clearly, when you click on the macro, you must be in motion (hold down any key W, A, S,D) after the shot, the macro itself will knock down the animation of the last shot and «reload the weapon» you will continue to run.
