Well, not saying a .338 Win Mag doesn't have recoil in a 9lbs rifle, just saying I think the .358 Norma could generate more if one pushed the 250gr or 275gr hard. As it stands with a factory load in .358 NM using even the 250gr bullet I believe you are correct by pushing a 225gr .338 bullet at that vel. But.. if you push a .358 NM... 250gr to 2850 fps, which it can do, it's up in the 40.0 plus fpe in a 9lbs rifle. No dog in the fight, just observation.
