Givin all the same conditions, the heavier bullet will recoil more, fact of physics. But, givin the shorter duration (barrel time) and faster acceleration of the lighter bullet, it will have a sharper felt recoil. Kinda like a slap in the face verses a heavy push. I worked-up a sheet of .357 loads for a magazine article way back in the seventies and had one 110 gr. load that clocked 1635 fps. out of a 6" Colt Trooper. The actual recoil of the gun was not that bad, but the felt recoil was brutally sharp. The 158gr. loads with the same powder (not the same charge wt.) had more actual recoil, but were more of a punch than a slap as far as felt recoil.
