Many boresight devices just plain and simple are made to lighten shooters pockets and don't work.
First set up a sight in target with 1" squares at 100 yards.
Then put the rifle in a rest, cradle or sand bag it to hold her still.
Now pull the bolt from the action and look down the barrel through the bore and center it on the target, when doing this make sure the rings of light you can see down the bore are concentric and even with the targets bullseye centered in the bore.
Studying carefully look back and forth between the bore and the scope until you can see the bullseye is centered in the concentric rings of light shining off the bore and the cross hairs have been moved to the bullseye as well.
Move the target to 50 yards, make sure the rifle is good and steady and fire one shot. It should now be easily on the paper.
Steady the rifle again and center the crosshairs on the bullseye. With the rifle absolutely still move the crosshairs to the bullet hole you just shot. ( sometimes it helps to have someone else turn the dials)
If you successfully held it steady and moved the crosshairs to the bullet hole then the rifle should now be zeroed.
Shoot a couple more to confirm and make small adjustments as necessary.
If you get a few shots in and its wandering then stop. Ammo is expensive. You most likely have a problem with the scope or mounts.
This can also be done by doing the old school bore sighting part by looking out a window at most any distant object and centering it in the bore and moving the crosshairs to that object. The further the better.
Good Luck
