I have not used these myself.
but reduced loads =less recoil yes.
you just won't get the distance or energy hitting power or as flat a trajectory with such as normal loads would.
think of it as say a muscle car with a 454 and two four barrel carbs,then you drop them for a single two barrel carb.
yes it will stil lrun and drive etc but just won't have the performance it did since you reduced it .same as for rifle,
pistol, shotgun or any ammo.hope this helps ya.Kurt.
