Yes, it would be with hand loads. I suppose the best way to test this is to take each load to pressure signs for a max velocity. Then you could find the "best" (most accurate and velocity) load in each and compare as well. Now to convince the wife I need to spend 4k for scientific purposesWith factory ammo you may be correct, but in my opinion, with hand loads, the 300 WM really shines with projectiles in the 200-220 grain range. I have loaded for the 300 PRC, and I would agree projectiles in the 225-245 grain range might be ideal, but it would depend on how one defines "ideal."
