I recently bought a Tikka T3 Hunter that came with a Nikon Buckmaster. I have a pile of Canadian Tire money and was thinking about upgrading to a Burris Droptine. Both scopes are 3-9. I am a huge fan of the Burris Fullfield 2 scopes so thought the Droptine may be a good option. I know very little about the Nikon other than it look to be a less expensive scope. Is this a worthwhile upgrade? How do the 2 scopes compare?
