Making camera like Hellmet

How could I make sway like this?

So for I while, I’ve been sticking to springs for sway. For a while now, I’ve been looking at @BIackShibe’s work. I really like how he did his weapon sway. It looks like something from a Triple A game. I was wondering, how could I create an effect like this?
