How would I make this bullet effect?

This is what I want my guns bullet effects to be like:

But I tried making with beams and trails but they just spawn in the sky and don’t even come out of the point of the gun but a few seconds after it? How can I do it? I’m using fastcast

Perhaps you will get more help in this Scripting Support area if you were to show us the script you are using with some prints in it to confirm the process flows as you expect and values of any variable that may effect the flow.

Well, seems like a particle emitter is doing the smoking job. Try that.
