Hi! I think this is what your looking for so ima say this.
Explanation:
It honestly really depends on what type of style your writing in, Like if you were writing like an informal piece it would more of like "<em>BANG!" </em>or maybe like a <em>"BOOM!"</em>.
If you want like a gun bullet to go pass something you could write like
<em>"WOOSH".</em>
