Bore sighting will get you on the paper. I have never had a rifle hit dead on with just bore sighting. I have a Leupold Zero Bore Sighter.
It can get you on the paper. What I can do with it is once I zero a rifle I can put it back on and record where it places on the target. I can then use that to check my zero. However before I go hunting I am going to the range and verifying that the rifle has held zero.
