Consider the following sentences
She did not feel the bullet going through her skull.
vs
She did not feel the 9mm NATO Parabellum lead bullet going through her skull.
vs
She did not feel the nine millimeter NATO Parabellum lead bullet going through her skull.
I have the impression that the last two examples have a beat dilation caused by the added details. The last one in particular seems to slow down even further due to the choice of longer words. On the other hand, when re-reading the last passage I find it almost cartoonish and somehow lacking the pathos of the first sentence.
I would like for the beat to slow down as if the bullet were to take forever to go through the skull, but at the same time I wouldn't want to lose tension in a mound of details.
How can a beat dilation be created and extended without detracting from the main event and without becoming comical?
