There is nothing wrong with your scope. Most scopes at higher powers cannot be fully focused or sharp at 25 yards. Parallax on many centerfire scopes is set for 100 or even 150 yards.
If you wish to continue shooting at that distance and have the target in perfect focus, you need a scope with an adjustable objective, side focus or a rimfire model with shorter parallax.
