If the OP really means the OQ
"with same 'powder' load, which bullet weight has more recoil? A lighter one or a heavier one? 115gr or 124 gr? 9mm?"
Then the heavier bullet will have the greatest recoil.
For many powders, a maximum load for a 147 is a starting load for a 124 and a powderpuff load for 115 grain bullet. Velocity is not much different so the heavier bullet will have the most momentum.
