There are no bullets in CoD. Just things called "hitscans." Theyre basically little signals in game that takes away a persons health.

But to answer your question, there is no bullet damage drop. The M16 (Just an example) is a three shot kill at any distance. From all the way across Wasteland to the little cubbie hole on Rust.
