As suppressors become more commonplace, I think the 300wsm is seeing new life from folks that want a shorter barrel and still want to drive a .30 cal bullet faster than the 30.06 can muster.
This is what caused me to bring home a Christensen Arms Ridgeline FFT in 300 WSM. It has a 20 inch barrel and my Silencerco Harvester EVO gives me a barrel length that is very handy out of a blind. Recoil is negligible, and my limited experience with on game performance has been very encouraging.
