I strongly suspect if one loads cartridges to same performance level and use rifles of same specs the recoil will be identical. Anyhow the .300 WinMag is far better choice. "Weaklings" can even buy "Reduced Recoil" loads if they want to. If one lives in wonderful place like USA and has enough cash they can have Superior Ammunition "roll" their cartridges can any reasonable level they desire.
