3rd Person Aim at Center Screen/Crosshair?

I’m working on a 3rd person shooter, and I’m having trouble getting the character to aim at the center of the screen. Below is the blueprint I’m currently using to try to achieve centered aiming.

And below is the result I’m getting after the character spins around spastically to reach that position.

I’m not sure what I’m doing wrong, here. What would be the right/best way to go about making this work?
