The rifle you received is solid and accurate. If you do any modifications to the package I would look to a better quality scope. If you are satisfied with the scope on the gun then use it as is. If you decide to change the scope look to the Weaver Grand Slam, Leupold VX-III, Bushnell Elite 4200, Burris Signature Series, Nikon Monarch, Zeiss Conquest, or Swarovski. As far as ammo goes any of the 150 gr. loads available from Hornady, Remington, Winchester, or Federal will take deer effectively.
