I don't know if one exists, but I don't think it would actually be that hard to make. You'd need to change the conditions for the Camera Paths so that the one for the bullet-chase cam has a 100% chance (or however much higher probably you want it to trigger at).
In the GECK, Camera Paths are accessed via the ''Gameplay'' drop down menu on the menu bar at the top of the window (it's the ''Camera Paths...'' menu item). In the ''DefaultHits'' category, the bullet-chase cams tend to have ''BulletFollow'' in their names. Their percent chances to trigger are all over the place, ranging from 10% up to like 75%, depending on range and other factors.
