Rifle recoil is the result of the conservation of momentum, momentum is the product of velocity and mass. A 180gr bullet at 3,000 fps carries about 20% more momentum than a 140gr bullet at 3,200 fps, even using the same powder charge, the .300 is going to have significantly more recoil.
I thought my .270 WSM had pretty reasonable recoil given the velocity, very loud but not too punishing at the bench. The recoil of my 140gr load at 3,200 fps struck me as similar or sightly less than full power 180gr .30-06 handloads, and the calculators back that up.
