One can bed the rifle in a way which is unobtrusive yet totally effective. I would not be too concerned about lug contact. It is most likely the left (top) lug which is not touching and this is because the sear lifts the rear of the bolt up when the rifle is cocked. Since rifles are cycled more empty than loaded, you get this wear pattern. When the rifle is fired, the lug makes contact when the trigger breaks. Not an ideal situation but there it is. GD
