well....u could load down for her to target shoot and get used to the rifle and then go out by yerself and use a normal charge and see how many clicks u gotta move on the scope to get it zeroed with the higher charge. then wenever u go huntin load the gun for her with a normal charge and reset the scope and she wont even know....

the adrenaline will be pumpin wen she shoots the deer so she wont even feel it.,
