My guess is the op does not have the parallax adjusted correctly.
2 ways to fix that...
One point the rifle at the target on a rest and without touching the rifle, move from side to side and up and down while looking through the scope.. if the reticle is moving, then adjust parallax until it is not.
second method... when looking through the scope, bring your head rearward until the edges of the field of view in the scope get fuzzy, then shoot when that fuzzy out edge is centered.
third actually is to do both.
