Depends.....you'd have to shoot it and see. When you zero with a particular ammo your zero is for that particular ammo. Changing ammo or even changing lots of nother same ammo can affect your zero. Even changes in weather conditions can affect it slightly. This is why its always nice to double check your zero when you have time. All these changes can be small, however I feel its good to know since the changes typically require some sorta adjustment to optics.
