I reckon if I already had a 30/06 but want to go something larger going to 300wsm or 300 wm isnt worth the gain . My thoughts if wanting to stick to 30 cal would be go to 300weaterby at least it has a fair jump up in Velocity to make it worth while. The down side would be more expensive ammo and perhaps not as readily available. Otherwise the next step to me would be 338 wm , 338rcm or 338/06 using 225gr bullet dependant on your recoil tolerance.
