See if your rifle is truly MOA with this sharp, beautiful, printable target! The circles on the target are exactly one inch round, so if three shots are within the black circle, then you have yourself truly sub-MOA rifle. The crosshairs on the circles extend one inch up/down and left/right, so you can see just how far your point of impact was from the circle without having to go downrange (allowing you to adjust your scope accordingly).
Be sure to print this target at 100% (do not scale down), or else the circles will not be 1″ round.
