Since you are "on paper", stop bore sighting! Confirm your base and rings are tight by trying to add torque. If none are loose...mind you, the torque is pretty low.
Sight in at 100. Confirm at 200 - 300 and then at 25 again.
Basically, the issue is probably the scope. Somebody needs to communicate to Walmart that there are no good free scopes! It is probably parallax. A 100yd 0 will put you near the std 150yd parallax setting.
It maybe wacky until you get a decent scope and mount.
