Check to be sure that your base mount screws are not bottomed out on your reciever, that would make you think that it is tight, but it will in fact be loose.
Have you used that scope on any other rifle with decent recoil to be sure their is not any internal issues with it ?
Check all action screws for tightness, not overly tight though.
make sure the barrel and rear tang are free floated. You should easily slide a dollar bill between the barrel and the stock all the way to near the recoil lug.
I am sure i am missing some other stuff that other folks will mention. That 165 gr fusion ammo should shoot very well for you, you definitely have something wrong.
good luck.
