The reason that we have new cartridges is that, for the western hunter, many old cartridges are [bleep]. A .30 Nosler fits in exactly the same rifles as a .30-06, but substantially extends the ranges at which game can ethically be hunted.
New cartridges are generally caused by one of the following:
Moving to a shorter action or replacing a cartridge that was designed for an odd size intermediate action for which good actions are not available
Moving off an incorrectly chosen slow twist to a correct fast twist
Removing a counterproductive belt
Cartridge shoulder/taper improvement giving better performance for less recoil
Fixing an OAL, shoulder position, or throating problem
Complying with specific state hunting regulations
