You are probably canting the rifle towards your face (assuming RH shooter) and have zeroed for 30yd.

Everyone does this to varying degrees (literally).

Only by using a spirit level on the gun or scope will this be exposed, and you will be surprised, what you think is level without doubt will be off, and level will feel odd.

Crosshairs no help as scope may be canted and in any case in the field there is little to align them to.
