If you are truly going to limit yourself to two main rifles that you'll use, I'd recommend building. Costs more, but limits the concessions...
As far as cartridge choice, if you are set on the 300WSM for the elk+, I'd look for a chambering that has a very similar trajectory to your favored load. For example, a 6.5 Creedmoor 130gr bullet or a 270 150gr bullet would track very similarly to a 180gr of same make out of a 300 WSM.
